Modifying a Portable Numark PT01 for HiFi Playback - Vinyl Community

Modifying a Numark PT01 to hifi quality. When you own a cheap turntable you often hear the warning "Don't ruin your expensive vinyl on that thing!". Why does it ruin your vinyl? What can you do about it? In this video you see a modified Numark PT01 safely playing expensive records ;)

[@SouvenirDin24]

Just stumbled across this video. I've been improving my Crosley. Before anyone comments, they don't chew records! I have a Philips hifi with the SAME BSR turntable mechanism and tonearm/cartridge and I still own the vinyl and it's not chewed despite being played for 40 yrs! The bit that chews your record is the cheapo needle that is often shipped with the unit - I've replaced that with proper diamond one, upgraded the ceramic cartridge, added counterweight, upgraded speakers, added high impedence pre-amp for the ceramic cartridge (omitted from most cheap turntables which makes them sound flat), new main amp etc. Anyway, my Crosley sounds good for a portable record player but I would like to try a magnetic cartridge on it to see if I can get it even better. Obviously the pre-amp will need swapping with a pre-amp suitable for the MM cartridge. Just waiting on the bits to arrive before I try and retrofit an audiotechnica magnetic cartridge to it. Wish I had a 3D printer ;) You could sell those brackets on ebay - would make a fortune ;)

[@vwestlife]

It's not the ceramic cartridge that wears out quickly, it's the sapphire stylus it comes with, which only lasts about 1/10th as long as a diamond stylus. Upgrading it with a diamond stylus will solve that problem. The tonearm of these Numark and ION players has anti-skating and tracks at 5 grams, which is the recommended weight for the cartridge they use, and below the 6 grams of tracking force that vinyl records were originally designed for. The spring is part of the design of the tonearm and allows it to play a record at any angle, even upside-down! (See my video "Amazing gravity-defying turntable" for proof of that.) Overall these are not bad record players and in normal use they will not damage your vinyl!

[@XjunkieNL]

Thanks for the comment. Agree with you a 100%. A sapphire stylus will not damage vinyl. Only maybe when completely worn. Most probably the high tracking force will not have too much effect. Although on my unit it was above the 6 grams you mention. My main goal was to improve the sound quality. I wanted to have at least a moving magnet cartridge. Instead of changing the sapphire stylus to a diamond version. I love this little turntable. And it's fun to use. Cheers. /Paul

[@XjunkieNL]

Just watched the video. Incredible! Temping to put the old arm back and give it a try ;) /Paul

[@dealingwiththedarkestsideo5392]

About playing upsidedown, that s great, probably the only record player that does it, unfortunately I have two and none can do that, they r the first models, the USB ones, why u think this is so? Could that be fixed?

[@dealingwiththedarkestsideo5392]

R we sure it s a spring or a magnet? Apparently springs r for the tracking force. By the way congrats 4 ur excellent video. Is there any way to get the ones with that brand? No sure right know the latest Numark does that too

[@vwestlife]

@@dealingwiththedarkestsideo5392 The PT01 uses both a counterweight and a spring. The counterweight balances the tonearm and the spring applies the tracking force. If the spring has gotten detached or is missing entirely, it will still play in the normal position, but will no longer be able to play records at any angle or upside-down.

[@redcomusic]

I had that Numark PT101 and used it to rip and upload my needle drop videos ten years ago. I don't miss it; always thought it sounded dull with the included stylus. I never measured the tracking weight, but always felt it tracked very heavily. But I did like the pitch control so I could sync it up with a CD to get the exact rpm. - Red

[@XjunkieNL]

Thanks for stopping by, Red. Tracking force, especially with the standard attached spring, is crazy. I had to add a lot of weigh at the back of the arm to get somewhere in the ballpark. What a great idea to use a digital track to set the correct speed. Gonna try that. Cheers. /Paul

[@Paneeks1960]

When it comes to anything audio you are brilliant Paul. Now did learn most of this tweaking/modifying or upgrading stuff by researching it online? Your knowledge in electronics is very sharp. I dig how you even changed the speaker. Wow, 200 spins with that lithium battery? Jeez, it really does sound a lot fuller and also a bit punchier. I did not even know that the portable Numark's came with a pitch control. Funny, I was just going to ask you if you thought that the $100 was money well spent figuring the turntable cost was similar. But you answered my question before I could type it in. {smile} My theory is this: No amount of money is too much if it is bringing you true happiness. Thanks for sharing this one Paul. I thoroughly enjoyed it~ Rob/Boston

[@XjunkieNL]

Hi Rob. Always enjoy reading your comment. This upgrade is a mix of what I have seen others doing and my own ideas. Most make a little portable scratch table. I think I'm one of the first modifying it to fit a cheap hifi cartridge. Half the fun is thinking and fiddling about. It was the first time I could play with a 3D printer. This made the job must easier. Money wise I spent a little more as intented. All the best. /Paul

[@akn6803]

Finally found such a video - I searched for a few days if anyone did that, such needed modification for these portable record players (and I'm talking especially about all the Crosley's and their like) I think it's very good you recommend to make that upgrade. I think it is disgraceful to see all these trashy new record players use the ceramic cartridges - I think, especially if it's done in mass production, including magnetic cartridge and adequate MM pre-amp won't increase the price of one unit that much - it's all about greed. I'm sure if people will know the benefits of preferring MM cartridge many if not most of them will pay a few more $$ for that setup! Well done @X junkie NL !!!

[@XjunkieNL]

Hi! I agree. The minimum on these turntables should be a conical MM cartridge. It will give so much more joy to the owner playing vinyl. And can be the real start of the vinyl addiction :) Luckily this modification is universal and can also be done on Crosley's. Thanks for the comment. Have a great weekend. Cheers. /Paul

[@gregoryaquelalijonessr2110]

I found what you just said as profoundly HARLIROUS! Why? Because I took a screen shot of your video and looked more closely at what was missing like a finding Waldo puzzle🤣😂. 2nd I took a closer look and worked out the ohm, and I hat each capacitor did. Thus coming up with the removal of one leg on each, then flipping the board over, joining the capacitors as one and then running a ground wire that a soldered in, gave me that pure, high quality & clarity I was seeking! Secondly, I placed a small retrofitted slither of Dr Suzuki plastic film over the four felt padded supports so when I place a slip at on before the album it reduced the amount of torque required to spin the album thus impacting tracking requirements getting a more closely attuned “pitch & key” result in sound quality. Thanks for providing me a small key to unlock the other ideas I was contemplating with a formula for solving those equations. Taking something that is cost efficient and turning it into an item that provides quality is a life’s quest. Peace and blessings!

[@XjunkieNL]

Did you find Waldo? He was hiding behind C8 and C18 :) I will also look at the felt padded supports. Thanks for the tip. /Paul

[@DeeJayBulldawgPurp]

@@XjunkieNL YES!!! Okay 2nd part, I was noticing how you performed your battery installation. Did you select to also connect the battery to capacitor on the boards? It's the black three pronged power cap that sits on the same board with the input for power supply. It appears that you ran spliced cables and adapter to the battery pads. Just wondering if you added some other alterations there.

[@Energyflash1979]

Excellent, I have just installed an Ortofon cartridge and couldn't understand why it was so quiet. I never knew that ceramic stylus were louder so at least I know I require a pre amp now. Do you know how I could reduce the humming noise?

[@XjunkieNL]

Hi! Cool to hear you've taken the first step and changed the cartrigde. There is no way around it, you need a preamp to increase the volume. Did you have the hum the whole time, or since you changed cartridges? Maybe it's now more noticeable with the low level volume of the music. Cheers. /Paul

[@Energyflash1979]

@@XjunkieNL it always had a hum noise but iv only ever used it with a power adapter and not batteries. I wonder if it could be interference from the AC/DC power source? I was thinking of getting a rechargeable battery like yours too. Did you just strip back the cable and solder the wires to the + & - springs in the original battery holder?

[@XjunkieNL]

@@Energyflash1979 That must be it. I've been using the rechargeable battery for ages. A great modification. The battery seems to never get empty. No, you can't do it that way. The voltage is a little to high, you have to reduce it to 9 VDC.

[@QoraxAudio]

Interesting, I've never heared of Visaton before. Don't forget to select an amp with a RIAA filter built in. A cheap 20 euros Behringer PP400 (35dB gain) or one of many rebadge duplicates will do fine in most situations as a compact internal Phono preamp.

[@XjunkieNL]

As you already picked up on the Dutch accent, on Conrad.nl the Visaton speakers are available in many different specs. Great replacements. It's funny you mention the RIAA filter. It turned the original one didn't have one, it seems most sapphire needle don't need it. The Behringer would be a great alternative, and a little cheaper too. Cheers. /Paul

[@QoraxAudio]

@@XjunkieNL Hmmh interessant, ik shop wel eens bij conrad, maar eigenlijk nooit voor audio componenten, meestal voor algemene elektronica componenten. Zal ik volgende keer eens naar kijken dus! Als die draaitafel standaard geen RIAA filter heeft, betekent dat waarschijnlijk dat de saffier stylus simpelweg te slecht is om die lage tonen fatsoenlijk weer te geven, of de standaard speaker te klein lol RIAA filters zijn namelijk om de originele informatie weer terug te krijgen van vinyl, aangezien er een negatief RIAA filter (Highpass-filter ipv lowpass-filter) wordt gebruikt voor het maken van de masters/matrijsen. Betekent waarschijnlijk wel dat je nu een flinke upgrade hebt tov. wat het was; ik wist niet eens dat er nog stock draaitafels met saffier uitgerust werden, het klinkt voor mij als iets uit een vorig tijdperk 😜

[@XjunkieNL]

Waarschijnlijk de enige reden dat saffieren naalden nog worden toegepast is de prijs. Ook is het signaal veel sterker, makkelijk 10x meer, dus kan de versterker eenvoudiger. En hij vervormt het geluid, zodanig zelfs dat het beter klinkt zonder riaa filter :) Dus als het goedkoop moet zijn, is een saffieren naald de oplossing ;) /Paul

[@QoraxAudio]

@@XjunkieNL Geweldig! zo slecht dat het juist beter klinkt zonder filtering haha 10x is trouwens wel fors.. 10x in dB of in milivolts? Betekent in ieder geval wel een goede signaal ruis verhouding op de lijntjes tussen de cartridge en voorversterker ;)

[@XjunkieNL]

Als ik het goed onthouden heb, is de uitgang van een saffieren naaldje ergens tussen de 0,1V en 0,5V. Hahah, van het hoog valt zoveel weg dat de bas niet hoeft te worden versterkt ;) /Paul

[@jukeboxsmurf]

Beste X junkie ,dankjewel voor uw instructie video .Kan u me uitleggen waarom de 2 condensatoren verwijderd moeten worden ? Kan de uitgang van de pre amp niet terug aangesloten worden waar de oorspronkelijke tone arm was aangesloten ? Dankjewel ,Marc

[@XjunkieNL]

Hi Marc. Wat je zegt kan in principe. Alleen loop je tegen twee dingen aan. De totale versterking wordt te veel, doordat beide het signaal versterken. Of als alternatief dient de nieuwe preamp met een veel kleinere versterkingsfactor werken. Deze zijn echter niet zo makkelijk kant-en-klaar te vinden. Ten tweede heeft de interne pre amp geen RIAA ingebouwd. Met een saffieren naald geen noodzaak, met een MM element wel. Hierdoor is het het eenvoudigst de interne preamp te overbruggen. Hoop dat dit een beetje helpt. Fijne feestdagen. /Paul

Wow Paul! This was an excellent video, you explained everything very well! Now I do have one question: is it just the styli that needs changed at around 500 to 1000 hours?

[@XjunkieNL]

Hi Lis. Hope you have a funky friday :) It depends a little bit on the type of cartridge. Many MM cartridges have the possibility to swap out only the needle. MC cartridges most often, because of their construction, don 't have this option. By age the rubber damping inside on both types will dry out, but I guess this takes many many years. All the best. /Paul

May i ask u please to tell me how to get rid of the hum when the platter spins? I bought three Numark PT 01 USB from different sellers and the three have the same problem. My technician doesn t know how to get rid of it, even tho he fixed very well the unsteady speed of two of them. The third one I bought today has the same problems: The noise when the platter spins, and the unsteady speed. Is it just a coincidence?

[@XjunkieNL]

Hi Markus. Sorry to hear about your troubles. I have the original PT01, not the USB version. As far as I've seen on the inside there is a ground connection between the motor and aluminium top plate. Maybe double check this connection, or remove it. By the way do you have problem with batteries or connected with the power adaptor? Yeah, speed can fluctuate a bit, just be sure to not push the record too hard on the spindle. Hope this helps. Cheers. /Paul

[@markusziman363]

thank u very much for your interest, as this issue is mostly ignored by everyone except you so far. What is the original PT 01? I thought the USB model was the first one, back to 2006., the ones i bought are from 2006. I thought there are 3 models: the pt 01 usb, the pt 01 scratch, and the one with built in bateries. In this particular model, i dont think is a ground problem because this noise is only to be heard when the platter spins. I have two vestax handytrax, and the early version has a ground noise regardless of the spinning platter. Could you send me some link of your original model?

[@markusziman363]

I just posted the following in some forum related: Hello to all of you! I read all your comments related to the buzzing noise of the portable turntable Numark PT 01 USB. It seems that you give some suggestions and ideas but none of you apparently found a real solution, a real fix, and the real cause of the problem, 1 or did you? In a nutshell, 2 is there any real valid solution to get rid of the noise once and for all that is heard when the platter spins? (especially when using headphones) 3 Is "your" noise caused by the spinning platter or not? In my case it is, there s no noise is the platter doesn t spin. 4 So are we talking about the same noise? the noise that is heard when the platter spins? It seems that one of you got rid of the buzzing noise temporarily, but then it came back, and then suggested to remove a kind of a white square piece apparently related to the USB feature. 5 Does that completely fix the problem? 6 If not what does? 7 Did any of you find the real cause of the noise? 8 Did any of you completely removed the noise once and for all? There are many videos on youtube related to this turntable but as far as i know no one mentions this buzzing problem. This is the only forum and info related i found on the net. 9 Are there any more? I also asked everyone (Numark pt 01 related videos) on youtube regarding this noise, and apparently nobody has ever had any buzzing noise, because they either completely ignore my question and comments, or are asking me questions like " What kind of noise? " etc which makes me think they have no idea what i m talking about because they actually never had this noise. Some youtubers play records using this Numark PT 02 USB, and there is no noise whatsoever, none at all. 10 So what's wrong with our models? 11 Are they defective? I bought THREE Numark PT 01 USB from three different sellers, THREE, and ALL OF THEM have the same annoying noise that makes it especially annoying when playing some kind of classical music etc. 12 I´d like to mention another problem if i may, related to this Numark PT 01 USB model: The speed: It's uneven, and this speed problem is, as a matter of fact, something many owners complain about. 13 Do you have the same speed problem too? 14 If so how did you fix it? ( i'm not talking about changing belts, but using a new one and still have the same problem) Some technician fixed the speed problem in both of them, and when using a stroboscope, both 33 and 45 were ok. I didn t ask him to adjust 78 tho The problem is, the speed was uneven two days after, without using them during those two days, in both turntables. 15 How on earth is it possible that this turntable has uneven speed and buzzing noises and yet being satisfactory used by so many people who even invest almost 500 bucks in modifications, like pro arm forces, to be able to use pro stylus and cartridges)? 16 I mean who would even bother investing any money with a turntable that has a buzzing noise and an uneven speed in the first place? Expensive tonearms would not fix that as far as I know. 17 Who would do that investment having this annoying buzzing noise and uneven speed in the first place, and not even mentioning it anywhere ? 18 this buzzing sound appears to be only in the USB model and not in the scratching model? "The third model" , the one who has a built in battery has a buzzing noise too according to some youtuber who actually is very happy with the one we are talking about here, because his has no buzzing noise, but complains about the one he bought brand new with the built in battery because it does have a noise. These turntables are extremely affordable, 19 maybe that's why they have so many issues? 20 or it s just that we had bad luck and have defective ones? 21 If all of them had the same issues, why on earth people would talk so highly of them and invest money to replace force arms etc? 22 May i mention another turntable, the OMNI, who already has a pro arm force, and is more expensive. 23 Do any of you have one? And if so, 24 could you tell me if it also has the aforementioned problems? Which are: A) Uneven speed B) Noise when the platter spins C) "Ground noise" regardless if the platter spins or not 25 May I mention the Vestax Handytrax? I have two. One of them, the first model, has a noise as well, but not related to the spinning platter. The noise in this one seems to be "a ground noise" which increases when touching the surface of the turntable. It also has an uneven speed. And the other one, a white one who is a slight different new version, has no noise whatsoever, but an uneven speed too. 26 Who would be ok purchasing and using a turntable that doesn t even offer the very minimum requirements? Minimum requirements meaning playing a record with the right speed, even speed, without the extra annoying noises, and without damaging the grooves. I would be more than glad to pay more money for a light portable turntable with exchangeable light batteries, that would not damage the grooves and needle with excessive weight, and would spin at the right speed, even speed, and without annoying noises of any kind. Both the Vestax and the Numark are too heavy when using batteries because they require a lot of batteries that are not rechargeable, too heavy, and not environmentally friendly, unless there is another option, 27 is there? 28 Am i asking for too much? am i being irrational? The OMNI seems to have all basic requirements according to the informative emails I received from them (HeadacheSound brand) but after all the stress and wasted money and time invested in the aforementioned ones, I have my doubts the OMNI will fit the, again, basic requirements, so I have my doubts. I hope some of you will kindly provide the theoretically simple and practical solution, a real one, in order to get rid of the buzzing noise once and for all. Thank you very much. Feel free to contact me here too: [e-mail]

Hi Frank. Sorry for my late response. I had to check what preamp I used. As I remember now, I did use a preamp version for the USB version from Bihari.

Thanks for the comment. My answer was more directed toward the speed inconsistency. Usually not a big problem. On music with piano solos a little bit more of a issue. Cheers. /Paul

[@nomoreslogans]

Hi there. Just want to ask. How to disable the built in speaker when using active speaker? Thank you

[@XjunkieNL]

Hi! I've no experience with active speakers with my PT01. Is the internal speaker perhaps disabled when plugging in a fake headphone jack? /Paul

[@nomoreslogans]

@@XjunkieNL I use active speaker, but when I turn the speaker volume down but the sound from built in speaker is still exist.

[@XjunkieNL]

Okay, I understand. Would it be an option to just cut the wire to the internal speaker, or put in a switch. Maybe there is a simpler solution, but I'm not aware of it. /Paul

[@nomoreslogans]

@@XjunkieNL Im sorry. It's not from the speaker. The sound is from the center area of turntable.

[@nomoreslogans]

I've tried spinning a vinyl (without active speaker, only with the internal one), then I turn off the volume, but the sound still exist from the center area. How about yours? Btw, thank you for the response.

[@Mentalbeats]

Can you modify one for me since I’m not that versatile with electronics and wires? I’ll pay for the mods and parts. Is this possible?

[@XjunkieNL]

Hi Harold. I would consider it, if you got all the parts needed. But I think it would be quite expensive in the end doing it this way. Are you sure? The mods aren't that complicated. And I can help with photos. Already helped a few do part of the conversion. Cheers. /Paul

[@jusandrade]

do you know how i change the belt?

[@XjunkieNL]

Hi! Hmmm, nice fiddly job. Don't have a good tip. Last time I changed the belt, it took me a few tries. It's not really difficult, but you need a bit of luck :) Thanks for watching. /Paul

[@directorkid3131]

Would it be possible for me to add the lithium battery to my Crosley-like record player that doesn't have a battery at all? If so, how would I do that?

[@XjunkieNL]

Most probably, yes. It depends on the voltage the unit is running on. If it is converted to something like 9 Vdc. It's all about finding that spot in the circuitry and connecting the battery. Maybe with a voltage regulator in between. Being the first doing the modification is always tricky, as it can go wrong and warranty is out of the window. Good luck. Cheers. /Paul

[@directorkid3131]

Question; How do you install a battery? I looked up the battery, and I don't understand how you connect the battery to the record player. The only thing I can think of is sticking it inside the record player, cutting a hole in the back where the battery can stick out just enough for me to toggle the ON/OFF switch and plug in the charging cord, then, when the battery is done charging, plug in the power cord it comes with into the battery, and the other end into the record player, taking the power from the battery into the record player. I'm sure the way I came up with would work, but how did you do it?

[@directorkid3131]

The DC In spot in the back says 5V.

[@XjunkieNL]

Good question. It's something I didn't think about for your turntable. As my unit is already ready for battery power, there is inside space for 6 big batteries. It is exactly at this space the lithium battery is placed. Through the battery door latch I also access the on/off switch. You have to do it the way you suggest. Or make somewhere an access hole to reach the switch. You will need to use the switch, and cannot leave it switched on all the time, as it will loose it power. Do you think you can fit the complete battery inside? /Paul

[@XjunkieNL]

So you probably only need a 6 Vdc lithium battery. And use 5 Vdc voltage regulator or connect directly a 5 Vdc lithium battery. /Paul

[@ch0obo]

Can you send link for that batterypack?

[@XjunkieNL]

Hi. Easiest if you look on Ebay for "EU DC 12V 6800mAh Portable Rechargeable Li-ion Battery Pack fr CCTV Cam Monitor". That's the battery I used. Still works perfect. Good luck. Cheers. /Paul

Excellent. Would u add a 50% pitch?

[@XjunkieNL]

Hi! Never found the need to do it. The pitch control is already pretty big. Or do you maybe want to go lower in pitch? The turntable doesn't really like that, as it gets unstable. Thanks for watching. Cheers. /Paul

Hi Paul....... Always wandering what was the case with your turntable......... Considering your restless mind now everything is clear.......... You have a pretty, reliable and cheap portable vinyl player........... What is missing is records......... Haha I'm joking.......... Nothing is missing.......... Thanks for explaining your modifications............Het beste..........

[@XjunkieNL]

hahah, there are records, but you don't like JL ;) Nice to see you stopping by DJ Kit. Have a vinylious weekend. Cheers. /Paul

Sorry Paul you misunderstood me...........that's the trap with the comments.........i meant to say that you've got plenty of records...........nothing to do with your taste in music.........silly me ........all the best

No need for an apology. I kinda knew what you meant. Curious if you have a JL record in your collection? Voodoo Party maybe, it would fit nicely. /Paul

What if you don't have a 3D printer?

[@XjunkieNL]

3D printing gave me the opportunity to make most of the modifications reversible. But it's not essential for the mods itself. Also it was fun to explore the possibilities of 3D printing :) Cheers. /Paul

[@scupakus]

i dont see any point in this, you still have a wobbly platter, and rpm are stable as milenial feminist on pms.

[@XjunkieNL]

LOL...hahah, you offended 4 lethal minorities in one sentence. For sure, the speed stability is the next thing to tackle. Although since the modifications, I have gotten several copyright infringements with my needle drops. KZbin clearly more easily recognises the songs as before. Cheers. /Paul

[@scupakus]

women are actually majority and I refuse to go easy on society that could be seriously offended by joke. I love pts, i own one and ion pt usb as but i use it do dj so i know that rpm stability is mediocre at best. what kind of mods are you talking about now. i know theres a guy with pitch slidders mods on pts. i talked to the man and there's a lot of issues with mainboard and you cannot get the pitch right until you replace some parts @@XjunkieNL

[@XjunkieNL]

My current mods are focused on getting a better sound quality. Haven't done any on the rotational speed stability. My guess is, this is caused more by mechanical shortcomings as electrical. And needs probably some serious surgical procedure to correct. Haven't seen anyone trying to solve it. /Paul
