Tascam porta 02 customized pitch control

[@taotuhao5969]

Wow nice job! ( subscribed ) I have a Porta 02 MK2 and while its extremely clean and the inputs work, no sound comes out when pushing play. No except a slight humming sound. I would bet that it's a solder issue, but I have been able to find the schematic online. Any ideas/advice?

[@3rdisland477]

Thanks, watch my video below for this defect ther are 4 caps you have to replace, kzbin.info/www/bejne/jqCopYZ-l9KUZ68

[@dekalboy8816]

Nice . But how to make a little circuit board you show at 1,45 ? Which component exactly ? Don't understand . Thank you anyway for sharing. I also don't understand where exactly on the main board you have sold ?

[@3rdisland477]

It's just a variable resistor that connected to the capstan motor not more, the schematic is shown on 1:22 thanks for your comment

[@VolcanoDaisy]

3rd Island, thank you for this video. Where did you acquire the parts for this upgrade?

[@3rdisland477]

from the scap recorder machines

[@final_animal]

Wow, really clean job there, looks like it was made by the manufacturer from the outside. Nice choice of tunes as well! Do you have any idea how you'd go about modding this machine for pitch control but with a CV input? I have the same model, aiming to mod it so I can control the pitch/speed with LFOs (pretty much a beginner though when it comes to this kind of thing). Tnanks either way for the video! Subbed

[@yulyseus]

Exactly what Im looking for! Thanks!

[@spooktasticaparanormal]

Hello friend, I just want to say thank you for all you do for people who need advice. I was wondering if you knew where I might find a pitch control pcb for a Tascam porta 05. Thank you in advance. Paul.

[@3rdisland477]

thanks, what speed do you have? is it normal speed (4.75cm\sec) or high speed (9.5cm\sec)?

[@shawnedrington9916]

Does you 500 ohm pot heat up when running at low speed?

[@3rdisland477]

no heat at all , the motor consumes a very little current

[@stretchmetalfanclub]

Hey mine had this issue. Did u ever find a solution

[@tahmassive2380]

Hello, I would like to know if I can do this same in a tascam portastudio 05 hs, and if so, how could I do it? I would like to be able to listen to my tapes on it at normal speed, and also to be able to record at normal speed, could you help me?

[@3rdisland477]

Yes, sure you can, just watch my video below kzbin.info/www/bejne/nHeXZ5SXmduDg7s It is the same principle good luck

[@rrproducciones9545]

Great!!

[@deuceone7272]

my brother got one of these after his other one broke in 1995. it was black though, and the door was kinda broken, but it still had nice quality if you can look past the static.

[@JohnnyRock]

If it was black it was probably a Fostex

[@deuceone7272]

@@JohnnyRock it was one of these I remember. Had the reverse function and all. But the fostex was the one we had before. It was black for sure and even dated for the 90s. He managed to sell it to some guy who ended up making music on his own.

[@alexhauptmann298]

Hey, KZbin took down your "Tascam 644 home made power supply" video. Could you possibly upload it again without the music (since that's probably what the algorithms found to take down)? I'm trying to make a similar repair myself. Thank you.

[@3rdisland477]

Oh, thanks for informing me that , I will try to find it or make another video

[@vidstarX]

beautiful

[@534n4l3ts1r4m]

So, just to be clear, I’d have to swap out a different motor and acquire the pitch control knob elsewhere? Do you have links to these pieces anywhere?

[@3rdisland477]

All these stuffs are no longer in production lines , but you may find some on ebay or as parts

[@johnnyxblood]

I'm very interested in this mod, it sounds great! but I'm having a hard time figuring out what kind of motor to get just by looking at your video... I see "Mabuchi Motor", can you recommend a part number or description? Thanks!

[@flight-or-flight]

does it damage the motor after time?

[@3rdisland477]

never, it's only control the speed

[@stevenaltig]

Id love to do this mod with my tascam. Great video! But also dont get how you made this little „Pitch-Control Board“ you show at 1:45. and does CCW and CW of new motor play any role?

[@3rdisland477]

the circuit is very simple as shown in the schematic , CW& CCW is easy to fix by flipping the polarity of the motor brushs inside , good luck

[@stevenaltig]

Ok, so ill give it a try! Thx also for your tascam repair video, it just worked out fine!

[@stevenaltig]

I puted in a Mabuchi EG-500YD-2B (2000~4000RPM) and sodered this little pitch control unit with a 500ohm variable poti and a variable 200ohm (and more) variable resistor. The Tascam works fine! Unfortunatly the pitch effect is only very very small. How i said, im not a electro technician so i need to believe the guy in the shop which sold me the pieces i need to reach the control. Maybe you could tell me which potis and resistor you used.... Thank you very much!

[@bugmanuk]

Are those pots 500/100 ohm or 500K/100k ohm?

[@3rdisland477]

Watch the schematic diagram in the video

[@LerLoons]

I am looking for a replacement volume pot . Any idea the code for the one that is used in this machine ?

[@3laal3ahd]

LerLoons //You can use any pitch control pot from any cassette machine , these parts are available on ebay as spare parts

[@garrettlemons5657]

[@chenhuaiwang4224]

Hi There, I wondering if you accept order to do this mod, I living in Boston, please let me know thanks

[@3rdisland477]

I'm so sorry, I'm out of the US right now

[@fkaca1964]

Hi, I have the same model.But I have a problem with my device.The model I have is white noise at the output end when turned on.And the amount of noise changes when i adjust the phone level.How can I eliminate this noise?I want you to tell me anything.

[@fadaklondon]

문석민 What kind of noise ? some caused by power supply if not origina (piwer harmony) other caused by to potintumeter itself( sound level) need to clean with WD40, or durty head , clean by cloth and alkohol, wish this helps , thanks

[@fkaca1964]

Can I know your email?I would like to let you know the details of the product.Can I send you a photo or video and ask for feedback?

[@Alejandro-kz2zf]

the units normally have lots of hiss. ill try replacing the audio ICs with better spec ones, it should work.

[@bobjerome5390]

HI i done this to a tascam 238 i put a motor in as the old servo pcb was playing all the time no way am i playing 80 uk money each time that ic goe's bad i did a fix to a duel 6 track porta studio deck b the was running at 1 7/8 ips how they are the same speed 3 3/4 love to see fix like this

[@3rdisland477]

Thanks, will try to do some modifications with a cassette deck like 238, 234

[@bobjerome5390]

hi put the video on here for a week about the tascam 238 i pulled it because of the trolls i pulled out all the bad part and some new seal work to hold the new 12v motor there's a 12v line that powers the old servo motor i used this to power the new motor the pulley hole you need a 1.9 mm drill bit i used poly bar for the pulley very good fit on the motor you can use bass beware 1.9mm drills break easy in bass heat it up before you put it on the motor you know why i 100% can be done saved 200 uk money doing this and it will play the old 1 7/8 tapes as well i passing the info on as save me from them trolls bob

[@Blackeyedangel]

The only thing I need help understanding is why he's able to use a 9v motor on a 12v power supply. will this cause a problem?

[@3rdisland477]

It's 12v motor with a built in control circuit , not 9v

[@Blackeyedangel]

@@3rdisland477 Hey! thanks for responding. Looking on the side of the motor it says 9v dc. and i looked up the motor Mabushi EG-530YD-9B and it says 9v dc. I know that they can handle more voltage, was just wondering if you encountered any problems? Also, one last question, can you just install a potentiometer on the power side (redline) on the normal Tascam motor without any problems? Thank you for this wonderful tutorial. I subscribed.

[@Blackeyedangel]

@@3rdisland477 I was also wondering how you got away with this without reversing polarity? the motor says CCW on the side, and the traditional tascam ministudio porta 2 mkii motor is CW?

[@User173]

you should use a 12v motor. the Tascam is a12v center neg unit.

[@chrisgeorge3738]

Hard to tell from the tape you used, but this also slows down and speeds up the tape, right?

[@RockOfGreece]

Where do you live? My tascam is broken and everybody around here is useless and can't fix it. Would gladly send it to you

[@3rdisland477]

Living in NY, what model do you have , and what's wrong with it?

[@RockOfGreece]

@@3rdisland477 shit I live in Greece. I have the porta02 mini studio and I accidentally broke the adaptor and while I did that myachine fell down. While it didn't break (and I opened it and checked that everything is fine) it doesn't turn on with any other adaptor of same voltage and amps

[@3rdisland477]

[@rickesteban9239]

How do you remove the cover?

[@garrettlemons5657]

There's three screws on the bottom and the rest just snaps off

[@ugipugi467]

hey thanks for the video it`s great! the only problem i have is that my motor runs in the wrong direction :) now i am unsure if i can just switch the polarity of the motor. it`s the exact same motor you used in the video Mabuchi EG-500YD-2B (guess spindle motor).

[@ugipugi467]

okay i found out myself. you cant change direction of these capstan drive tape motors but you can flip around the rubberband an change the direction of the whole mechanism this way :)

[@els1f]

@@ugipugi467 nice solution 🙂👍 Where did you purchase the motor? These things seem to be getting more rare everyday 🤷‍♂️
