Here's an old school youtube saying: I see "Vintage Pioneer" and I click.

[@skylabsaudio]

lol! I like it

[@charlesengert6703]

I by no means consider myself an audiophile. I’ve owned a pioneer sx-1050 and that was my first real vintage audio purchase. I had a pair of advent OLAs that I bought for about a hundred dollars because someone painted them black… but man did that sound good. Furthermore, I started doing research on speakers. I ended up buying a pair of klipsch heresy’s that were in my price range and man it was the clearest sound I’d ever heard, but I wanted more bass. I tried a sub and that helped but was deadset on a pair of cornwalls. Fast forward, I finally got a pair of 1979 cornwalls to pair with the pioneer sx-1050 and WOW!!! Absolute game changer. No sub needed. So I started looking at amps and receivers again and got bit by the McIntosh bug. Shelled out big money for a vintage amp and preamp from the top Mac dealer in the world. That old pioneer blows the pants off that overpriced thing no question. Pioneer sx-1050 Vs. McIntosh 7270 power amp McIntosh c-31v preamp. Buy vintage pioneer. You won’t be disappointed.

[@johnvincent4048]

I've watched a lot of stereo reviews and most are for the high end equipment. Out of most peoples budget. Kevin is more like the "blue collar guy". It's not a slam. It's a compliment!!

[@oldpaint7533]

I currently own a SX 727 that I received about 25 years ago for shipping costs. I knew it needed work so I started work on it a couple months ago. Had to replace the tuning knob since someone tried drilling out the stripped set screws.What a pain. I built a dim bulb tester and bought a variac then spent several hours warming it up. It had been in my barn, wrapped in heavy plastic for that 25 years. Surprise...... it works. Needed lights so put in LEDs, cleaned the contacts and removed all the dust I could. The tuner section works beautifully. In the end it will need some transistors and capacitors. Anyway, just wanted to thank you for giving me some inspiration to try and get it running. Thanks!

[@c.r.sherman1795]

I've been watching you guys for a while now. I'm really thankful for your I formative videos. I got into the vintage receivers about a year ago and I have bought a few. I've also been learning how to refurbish them by cleaning the pots and switches, replacing dead lamps, setting DC offset and bias. I've even made a few minor repairs now. Having expert opinions on what is the best equipment to buy and what to look out for is enormously helpful. Thanks. I'd also like to make a thank you shout out to the guys on Audio Karma. This makes the hobby much more enjoyable.

[@kurtbader9711]

Have an SX980. Clarity and instrument separation are excellent. And, it gets loud enough to scare people while staying clean. Love the thing.

[@louiskuran5651]

I still have mine. Love it.

[@mguess]

Hi Kevin. Thanks for another fun video. As an owner of a SX650 I can definitely confirm the issue with the power/speaker switch. I was able to repair mine by dismantling the switch and reconditioning the contacts. Now it's working great, hopefully for another 50 years. Definitely a real pain, I considered giving up on it a couple of times. Unfortunately I didn't make a repair video on the switch. I didn't realize that it was a systemic problem.

[@tubical71]

Are you into DIY... : i usually replace these stuff using microswitch mechanics and relays....or LED/LDR a little DIY electronics and also a relay...in order to preserve the original usability but with jellybean electronics, which can be addressed anytime in the future... 😉

Sunday Morning Coming Down with Kevin. Starting my day off right. Thanks Skylabs.

[@makon2012]

First receiver i bought in 1976, SX-750, second was a SX-1080 in 1978. Gave the 750 to my brother and sold the 1080 in 82. I bought both at the Army PX for next to nothing. Sure wish I'd kept that 1080. Man did it sound good through some Bose 601s. Love the channel!

This part works perfectly as a replacement for the original(maybe better) speaker connectors; Mouser P/N 538-P-303H-CCT The center pin easily comes out. Click on the photo gives you a blowup of it .Digikey and others also sell it.

[@jimwhite9989]

I love this channel and I thought this video was super informative. I was actually chasing an RT-909 and the entire stack for that matter and never realized the FLD might fade or stop working. I really appreciate those you that keep the old-school electronics running and performing the repairs. Classic audio for me is at the same level as restoring old hot rods. Way to go SKYLABS AUDIO, only wish I lived closer to you.

[@frankflores3948]

Again thank you Kevin!!! I’ve owned vintage pioneer audio gear that fell under the issues you spoke about! I no longer own them, but you have the insight of the why!

[@WC0125]

What I learned about the speaker jacks was it was marketed as convenience feature before spring quick connectors. Sure there were banana plugs back then but the unique Pioneer plug prevented phasing errors and was easy to plug and go.I've never had a receiver with issues other than the missing plug. Losing the plugs was a such an issue Pioneer parts department sold them well into the mid 2000's. I'm glad I bought some extras back then as, like you said, the ones people offer now are junk.

[@skylabsaudio]

I like the phasing idea. Very plausible.

[@davidbono9359]

The Pioneer speaker plugs look almost like 2-pin DIN connectors, but the DINs have one flat "blade" contact and a round pin contact. Too bad they didn't use those, but maybe the DINs weren't available back then. Some vintage Bang & Olufsen receivers use 2-pin DIN plugs for the speaker connectors, and fortunately you can still find new replacements.

[@davidbono9359]

@@skylabsaudioAnother possible reason: It looks like you can attach the speaker wires to the plugs, and then connect the speaker plugs to the back of the receiver. That seems easier than trying to reach behind the receiver to connect the speaker wires directly to terminals on the back of the receiver.

[@markvalery8632]

I had purchased a used SX-727 that was missing a speaker jack. I bought replacements on eBay that plug in, although the plugs where about 1/16"-1/8" too long. So I ground down the end. It works fine for me, but I'm nowhere near being a audiophile. What should I look out for if I bought junk?

[@riflegurlsmom]

Kevin, love your videos - recently got back into vinyl and have learned sooo much from you! Thanks!!

[@skylabsaudio]

Great to hear!

[@alm5693]

Glad to hear you mention and recommend Midwest Speaker Repair in Roseville (a suburb of St. Paul) MN. In 2020 I had them replace the pots and caps in a pair of 1975 JBL-L100s along with replacing the original AWFUL spring wire clips with 5-way binding posts. They did a nice job. 👍

[@davealexander59]

I live in the Twin Cities, so I am lucky enough to be able to drive stuff over to Midwest Speaker and drop it off. They also have hundreds of awesome speakers for sale. They have repaired many speakers for me and they have always done a great job. Highly recommended.

[@skylabsaudio]

Thanks for sharing!

[@ronaldmorris3197]

Great information and excellent presentation. My first Pioneer receiver in 1975 was the SX-550, and it was a nice sounding receiver, and beautiful as well.

[@sarahwritehere]

Have wanted a Pioneer receiver for years now and this was extremely helpful. Thank you!

[@kthermistor675]

I completely reengineered an SX-650 two years ago incorporating a heavy duty relay into a reconfigured power switch circuitry. Worked beautifully!

[@Darrylizer1]

I have an SX 850 I found in a used vinyl shop that also does a side business selling vintage gear. I had it serviced and it's my daily driver. Got old tube gear too. Love it all!

[@DakTirCue]

Just turned 50 two weeks ago.. Bought myself a mint condition Sansui 9090 as a present to myself. My family threw me a surprise Bday dinner and then after dinner they gave me a most awesome present.. a mint condition Pioneer 1050! What an awesome day! So now I run my Pioneer with my digital stuff/streamers/cd downstairs.. and the Sansui ( much better phono stage) holds down the analog duty upstairs. I'm currently running the Pioneer with some Technics Sb-L300 three way speakers... Its a good match. Nice all around sound. Nice detail and tight bass. Still looking for my be all end all speaker though.... Probably a Klipsch Heritage.. Cornwall maybe? Although Im not sure I need 110W for those bad boys... LOVE LOVE LOVE the channel... been binge watching and learning a lot!!!

[@RUfromthe40s]

[@RUfromthe40s]

i had a sx-1050 and i notice the volume diference from the sx-838 , the sound was like putting some big celestion ditton from 1970 and i asked my father if he could borrow me his HPM-100 that he wasn't using but as in other times i couldn't touch is hi-fi gear but being older and having a family of my own , hurricane type , as fast as it happened it disapear but being a man he two days later appeared in my house and in the back of a ealy 70's ford taunus van glx in red was the hpm-100 and told me , take them later , let me see your home , after a couple of hours i told him maybe i'll get them now so you can drive home , he than tells me , you have to drive me home , and i was like ,ok but i only understood he was giving me the van and the speakers , was 1.6 engine ,at the time 1.3 engines were already piwerfull mainly because of the roads quality , so i was happy by the second time in my whole life with him and the van was metalized blue , rare to see a metalized paint , but what matters is having the sx-1050 with the big celestions and the hpm-100 and before midle of the scale volume the sound was really loud and not distorted ,this having a professional thorenz with a Sure needle and a x-165d from 1970 akai catalog and a just ofered ct-f1000 because i had bought a ct-f2121 and my grandfather thoughr it was weak but i was happy with it as i only recorded cassetes to play in the car i had already a 1973 bmw 2800 cs coupe

Kevin, thanks for another great video. As for the Pioneer speaker jacks, I use binding post adapters that plug right in and take standard banana plugs. Got them on eBay. They work perfectly in my SX-770.

[@craiglabreche9902]

Greetings I sgot back into vintage srereo equpment during covid and my first purchase was a Piomneer sx6000 and the receiver came with only on pair of speaker plugs. I don't know the answer to the practicality but for me it made it easier to connect the speaker wire the plugs , then insert the plugs, Less fumbling and a solid connection. Othe receivers and amps a bit more of a hassel pushing in the black and red buutons then feeding the wire through a hole or otherwise. I have bought several and was lucky to actuall find extra pugs that worked and others that did not. Odly our families first stereo receiver was a sx 6000 that was purchase in a PX in Franfurt with other equipment. The My mother and I took it to Paris for several years and eventually ended up in Seattle and it still works, never serviced, Your channel is great.

[@haqitman]

External power switch for old receivers with a rotary power switch is the way to go. All mine are connected to a power strip. Fingers crossed for the future.

I still have my Pioneer SX424 I bought new in 1973. I just had it repaired for about what I paid for it new, but I'm happy with the performance with decent speakers. It still has those plugs for the speakers in both the A & B sets. I don't know if they came that way, but the tech who sold it to me had installed resistors on the B set of plugs because he said it avoided switching past the B set on the selector switch with an open circuit. I am not an electrical engineer, but sitting here 50 years later, it sounds bogus. Thanks for your videos as they were great research before finding a repair shop.

[@krowmag69]

I concur on the HPM-900 and DSS speaker line. I had several versions of HPM's and the 900s were a step up from any other HPM speakers with the possible exception of HPM-150/1500 and the HPM-200s. The DSS 7 and DSS 9 speakers were another step up from theHPM-900s, even though the DSS cabinet veneer was vinyl. I was lucky and both pairs of my DSS speakers had good graphite cones. Another cool feature of the DSS-9's was the dual voice coil woofers. I had hundreds of speakers over the years and my DSS-9 speakers were at the top of my list of favorite speakers.

[@anthonylawrence60]

[@dtracy03ss]

As far as my SX1280, I had the Shop install a new set of modern Banana Plug speaker Terminals, one of the best upgrades ever. They did a complete Refurb on this Reciever so putting the Good Speaker hook ups didn't cost much at all!

[@pervertedalchemist9944]

Another thing is the excessive price gouging because of the brand. There are sellers giving it high prices just because it's a Pioneer. A few years ago, I almost walked away with a SX-D7000. The person who was selling it wanted a high price for it - despite it having some rust on top and had not been serviced or repaired at all.

[@alvinmarentes3315]

Totally dig the channel. Really liked the last part about the shirts. I saw one you wore in a previous video that had a guy in a chair getting blown away from the speaker with his tie billowing back, where did you get that...Love it!! Thanks for the content.

[@sabrowenie]

Was aware of the problem when I was given a 450 that was dead. Turned out it was a blown fuse. The switch was still good. Used fader lube instead of the usual D5. Replaced the lamps (hard wired!!) with LED. It’s in storage now but there’s a note on it to leave on and use a power strip. My main is an SX 3700. Fingers crossed that it lasts.

[@rickj1983]

The Vintage Pioneer channel is THE go to information source. I own a Pioneer SX-980 I bought new as a teenager and still have it and love it. The problem I have is finding decent speakers for it. Pioneer HPM 100's are very hard to find and to find an equivalent in today's speakers is hard. I almost wish there was a bookshelf speaker with the same kind of oomph.

[@skylabsaudio]

HPM 60!

[@supersportimpalass]

I have a pair of CS-V900D’s which were the video shielded version with a bucking magnet on the woofers. The nice thing about them is they are real walnut veneer and not the cheap vinyl like the rest off the DSS line. And yes they were not fun to re-foam but easily my best sounding speakers I own.

I own two SX-828's. Both of them have been in the family since new. Back in the mid to late 1990's I went to my local Pioneer dealer (so sad to see how many are gone!), and I bought many pairs of brand new old stock of the speaker plugs. I still have a few spares.

[@dicky7600]

Mouser has a plug that fits that series of Pioneer perfectly. I can't remember the number, but if someone needs it I can find out and repost.

[@mattspokane]

Here is why I can appreciate the pioneer speaker plugs. If you are in a shop and maybe have easy access to the back of your stereo, it's easy to plug in some speaker wires. For me, it's almost always too dark and I have to get light to the area and access to the space to fiddle with it. it would be nice to screw the wires in out in the open in good lighting. Then I just have to worry about getting it plugged in which I could almost do blindly. I think I would appreciate those even if I have to make my own replacements with a lamp plugs. I'm thinking I could send them down nicely so they wouldn't wear out the contacts inside.

[@isoukous1035]

Good tips about the switch of the SX50 series. I bought a SX650 six years ago. Lately the channels were not balanced. At first I thought there was a problem with the balance dial so treated it with some contact cleaner but with no success. I then found out it was the bad contact at the power/speaker selection knob. The problem was fixed by applying some contact cleaner there. After watching this video, I realized that this switch could one day failed to a point beyond repair. I am going to hook the receiver up to a power bar with switch, and use this switch to power on/off the receiver.

I had a lot of experience with the VFD displays. They look great when they are new, but they dim directly with they amount of time they are on. Many VCRs used these displays and since the clocks were on 24/7 they dimmed considerably in just a few years. There was a period when they were on large numbers of electronic products.

[@Audiorevue]

Actually I had a SX450 and yes the power switch did fail or I should say it was going out, but I followed a great repair video on here on how to fix the issue. All you got to do is look up SX450 repair and it's a British guy and he dismantles the switch and the contacts inside he cleans them and then silver plates them and that effectively solves the issue. I didn't silver plate them like he did, I just sort of bodged a bit and covered them in solder, and then sort of smooth that out and I promise you it worked like a charm, and I know longer have that receiver but it worked flawlessly after that and the guy I sold it to continues to say it's working fine.

You're absolutely right about the Pioneer DSS series being the best Pioneer speakers. I will never part with my DSS-7s. They've beaten out so many other sets of speakers--both modern and vintage--I've had in my listening room. It's just an all-around fantastic speaker. And, yes, I guard the graphite woofers like a fox.

[@skylabsaudio]

[@TheFRiNgEguitars]

Maybe overlooked but not directly the fault of Pioneer, the Darlington amplifier IC Chinese knockoffs blow. So if your Pioneer 80 series receiver needs one, it is hit or miss with the replacements out there.

[@bmboldt]

I had not thought about the power/speaker switch issue on the Pioneers but yeah, it is obvious now. Similar issue with my Sherwood. I just worked on a SX-727 which has that same switch and the speaker connectors. My SX-6000 also uses those speaker connectors. Another thing is the RCA connectors are too close together. It is hard to get decent cables connected to them. Love my SX-780.

Off topic: I really appreciate your background sounds and music. Some people put some really annoying, cheap, overused background "music" on their videos. Did somebody actually record yours for you? It really captures the feeling of vintage stereo, low, smooth tones, etc.

[@brunoprimas1483]

The good thing about the power switches is that there are two sets of contacts in the switches. Take it apart, flip 'em around, and away you go. Then, use a power strip to to save the new contacts. As far as the speaker plugs, they really aren't a problem. What is a problem with this era, is that fact that the bias trimmers love to short, causing the outputs to blow. Most models use 50 ohm trimmers and replacing them with multi-turn trimmers will save you in the long run.

[@LakeNipissing]

I have witnessed the rotary power/speaker switch faults many times! A few I can add - The SX-_50 series with the up-facing input and output connections are a bad design for getting filled with dust and becoming intermittent. - The voltage regulator transistors run fairly hot. Lift the cover off once in a while to brush / vacuum any dust or cat hairs, etc. - The SX-_80 series with the external heat sinks often have chunks missing out of the aluminum fins at the rear from being bumped or mishandled. - Is it possible Pioneer chose the removable speaker plugs to make it convenient to connect 'lamp cord' to the screw terminals neatly, in plain view on a table, and then just plug them in, instead of trying to do so on your knees at the rear of the receiver and end up with wire strands shorting, etc. ? Just a guess. Also regarding these speaker plugs, would a 20 Amp power plug with the --- | pins be a direct fit instead of twisting one pin of a 15 Amp power plug ?

[@skylabsaudio]

Good theory on the plugs! Thanks

Hey Scott! Have you heard DSS-9s? Man, if you havn't, you need too! Love your reviews. Keep em coming! What Pioneers are better, in your opinion?

[@stereoniche]

@@skylabsaudio Unfortunately, I have not yet heard a pair, I missed a set about 6 years ago, very much would like to add them to my collection. At the moment, the Pioneer TZ9 has the top spot in my speaker reviews. A little surprising to me since it has gone up against dedicated speaker companies' models, but there are some heavy weights coming soon. The TZ9 is about 5 yrs after the DSS-9 series and were developed by the Pioneer TAD group, quite a speaker. When Pioneer put their collective minds to something, they could create magic. One day I'll hopefully have a set of DSS-9 to pit against the TZ-9, will be quite a match! But, I do have some rare HPM series coming up soon, so let's see if they can give the TZ9 a run.

[@jimhines5145]

I have had my SX-780 on a smart plug for a while now. What I am wanting to do is remote control the volume knob. The easiest way to do this that I can come up with is with a digital stepper motor with a belt around the volume control and controlled from a micro ESP32 device. This would allow remote control from a computer or mobile device and also could have a calibration setting for min/max rotation.

'If' your main source is streaming, then, using a Bluesound Node or its equivalent, and feeding it via 'aux' or tape input, setting your amp volume, say at 10 o'clock aprox, then you can control your streamer vol via your app or Spotify, Tidal etc.. that's what I do. But of course, to listen to vinyl, I must get up and.. that's part of the pleasure of using a good turntable, wich I enjoy too. SylvainQc

My 780 has been going strong since the late 70s except for the 8 years it spent in a box in the basement.

[@jmad627]

Mine sits right next to my bed. It’s way too powerful for this little room, but I don’t care.

Ok I got a Pioneer SX-1980 trying to get it perfect brought a 2nd that had the AMP transistors converted chip pack any recommendations ?

[@Jonhobbs64]

Pioneer SX 950 is the most reliable receiver I have ever owned and I have had many

[@ReginaldDj1]

When it comes to those old speaker terminals people just replace them with update speaker terminals You have to rewire it but it works

[@tomdemaline8869]

I really like your channel very educational. What is you opinion of the Pioneer SX-800 series? I had an 828 that lost all audio. It powered on, all lights work just no output.

[@davidwell686]

I think the Darlington Packs are a problem too.

[@danielknepper6884]

They don't like low-impedance loads

[@WooferCooker]

He did have a video segment dedicated to STK packs, it probably would’ve been a good idea to talk about it here too, since most lower tier Pioneer’s use them.

[@skylabsaudio]

Almost all brands used STK packs, and since we covered it in the last Buyer Beware video, I thought I'd be beating a dead horse. However, yes. STK packs are a huge problem, and you are all correct about that.

Direct hit ... my first stereo was an 80s Pioneer stereo set.

[@mastrbuilder]

What is your opinion of the SX-D7000. My VFDs are still good and the amp section sounds great however however the tuner section has went mono. Stereo lites or stereo is not present. I took it to my local repair shop and they say the stuff to fix my tuner is unobtainum. I listen to streaming music mostly so the tuner issues don’t bother me. Have you ever serviced these?

[@modelrailroadingrevisited]

Kevin, I have an SX-525 with the speaker plugs you describe. Can you tell us any possible mods to get around using those plugs?

[@raygarafano3633]

I saw ur gallery of receivers, very impressive! The More-ants rcvrs would be Marantz if they had a reg tuner knob. Otherwise a very nice rcvr.
