- Step-by-step video showing how to disassemble, clean speed controls, and reassemble Pioneer PL-4, PL-5 and PL-7 turntables.
Thanks to beej at Audiokarma for his excellent instructions!
My PL-5 turntable is now fixed thanks to your video and some Deoxit D5 sprayed in the pitch control pot. It means a lot to me because I got this turntable as a high school graduation gift in 1982 from my parents. Now all these years later, its running pitch perfect and I am passing it down to my son, who just graduated from law school and thinks it's cool. Thanks Jim!
Glad it helped. Enjoy!
Thank you very much! Your video encouraged me to (finaly) put in order the servo of my 40+ years old PL-320. Same problem, same solution. Most of the instructions fit PL-320 at 100%! Some of my friends will also be grateful because I need PL-320 to digitalise some vinyl records of their youth. As PL-320 seems to be mechanicaly simpler than PL-7 (less buttons), I neglected your instructions to properly set the arm moving mechanism. So, right now, my PL-320 preforms the arm retract but does not switch off. In fact it does, but than it switches on again... So, I'll have to redo the exercise.
Glad it helped.
@@litzdog911 well, the mechanics disorder after the servo repair seems not to be a trivial challenge for myself. Could you please forward me the instructions you are mentioning in your video?
Got it by myself! In fact it is simple: with power off you perform a manually driven retract until final stage, when the handle lands on the hook. I missed that message following yout video yesterday, sorry. In fact, to do that you do not need to dissamble/reassemble anything.
My PL - 320 TT is now completely back in the shape, as new!
Thanks a thousand for your in-depth instructions!
I was able to heal my vintage Pioneer PL-4: It stopped to flutter as I followed your procedure. Kontakt Chemie's Spray Tuner 600 was my weapon of choice.
Pick up a PL-260 and the speed adjustment pot wouldn't do anything. Your video showed me enough to get it apart and get it taken care of. Thanks!
Thanks a lot for the video! I just used it to give my PL-4 a thorough treatment. I wish there would be a follow-up video concerning oiling and lubrication of the various mechanical parts, including cue lever and spindle. My TT has been demonstrating more Wow & Flutter lately, and I think i managed to lubricate it correctly and minimize the effect. I'm still not a 100% sure i did all i could... In any case, this video has been a HUGE help. Thanks for that!
thank you for such a detailed and patient example of how to do this! it drives me crazy to see people working in sloppy work shops with low light and being rough on the equipment! Nice job!
You're very welcome!
Thank you for your instructions Just cleaned my speed controls and set the speeds and working beautifully.
Also learned how to balance the tone arm, thanks again.
Glad to help. Enjoy!
You're a lifesaver! I've been trying to refurbish my parents' old turntable and hit this damn speed problem.
I had to take the motor all the way off since I don't have a screwdriver skinny enough to fit through the adjustment holes, and turns out it slips back into place as easily as the rest of the parts. Great engineering for something supposedly not user serviceable ;)
Glad to help!
Jim,
Got the steps from Beej, with your video I fixed it!! I have the PL4, so a little easier back together. No repeat button. Thank you.
You're welcome. Glad to help!
I just wanted to say thanks! I have a PL 730, same line as the PL 7 with the same speed issue. I was never able to locate that teardown document and getting the cover off was a conundrum. You saved me some tears!
Glad it helped!
Buenas amigo y lo arreglaste la velocidad del tornamesa yo también estoy con ese problema en 45 está lento
Easiest way to remove the strain relief is with what's called a button popper for automotive use. Took about 10 seconds and a lot less chance of damage. I picked up one of these today and used your video to go through it. It was a dirty mess when I started and tonight it's fully functional and a lot cleaner. AK is the best.
thanks a lot for this video! It helps a lot to disassemble my PL-6 which is like yours, the big difference is that it is auto-return only and not fully automatic and also it doesn't contain a wheel to adjust speed
Glad it helped.
Thank you so much , I had a PL 620 for restoration and I was struggling to take it a part , luckily I found your video so thanks again :)
Awesome vid! Thanks for the help on this one.
Excellent and clear description on opening up the turntable. I have a PL-7 with a repeat function stuck in the on position. That will be my next project. Thank you very much.
A very usefull video, thank you! I just received a Pioneer PL-4 with exactly the same issue. Now I know how to take care of it :)
Thanks man. I used this video to bring a PL-730 back to life for my inlaws.
Thanks for your detailed video! I just tuned up my PL-5!
Glad it helped you!
THANK YOU for helping me repair my PL-5 from 1982! Now that it works I am handing it down to my son in college who thinks this turntable is "vintage and cool". I have the matching SX-6 receiver too.
Spraying CRC QD on my speed control wheel " pot" and on the speed screw holes under the base has her running at a steady speed now. Note: Try adjusting the speed screws through the service holes underneath (by the index finger joint 36:20 )first because you don't have to disassemble anything.
My PL-5 was also stuck in an auto- on and off and restart loop. I cleaned the contacts inside and oiled the sliding parts. It works now. Maybe it was a contact on top of that huge plastic gear next to the spindle motor was hanging or it was some lever that needed cleaning. Or else it was the "tricky part" at 28:05 The lever attached to the start button has to be on the right side of the "pin" when you mate the top and bottom halves.
I just manually turned the motor and cleaned gears and lever and oiled until the tone arm finally behaved correctly.
Thanks to your video I’ve been able to resurrect my old PL4, which has been sitting in my basement for the last 20 years in mint conditions (variable speed problem aside); if you’ll ever stop by milan, beer’s on me.
Great Video. Thank you so much for making it. I was able to follow it very easily. Getting to see inside of my PL-5 and clean the appropriate hardware very useful. I can see how complicated these automatics are. Now I can see the benefit of a simple uncomplicated turntable where much less can go wrong. Thanks again!
You're very welcome. Glad it helped you!
Thank you give me an insight on dismantling Pl 120 cheers
Very nice work! Working on a similar model, except full automatic, so a few more linkages in there! But a very helpful video!
Great work, just what I needed
This was a huge help! Thank you sir!
Glad to help!
Just letting you know this is the second time I have had to use your video. You did a great job. I am mechanically inclined and needed to know how to take it apart. Your explanation was simple and to the point...... Kudos.. well done....
Glad to help!
Thanks for the video, just picked up a PL4 at garage sale for my son, and only issue was unstable speed and fine tuning dial all over the place. The instructions were perfect and now very stable speed and in perfect operating condition. I have always preferred manual turntables with auto return. Thanks again.
Glad to help. I'm sure your son is thrilled!
Thank you JIm! Your video was very helpful in disassembling and repairing my pl-930 that is very similar.
Glad to help!
Thank you fixed my uncles pl4 works great now.
Glad it helped!
Jim,
I went through your excellent video on my "new" PL-7. I did remove the motor board with the two speed adjustment pots for 33 and 45 rpm. I unscrewed the three screws holding it down, and unplugged the board , and this allowed me to apply the DeoxID properly.
I found that setting the distance of the control pin from the edge of the plinth really helped, adjusting to a distance of 90 mm. from the edge did the trick.
I was unable to get that little rubber stopper back inside the back end of the tonearm, so I will make do without for now, it seems more aesthetic than useful. Thank you very much more this tutorial!

Glad the video helped! Enjoy!
WOW - great job
Excelente video Jim... muchas gracias por dar a conocer como desarmar el tocadisco. Tengo el PL 430 y ahora podré desarmarlo. saludos.
hey Jim, just been working on my PL, this vid was a god send!! thank you Sir! :o)
You're very welcome!
Very useful , thanks
Thanks for the disassembly video! Pioneer PL-7 I must try to clean it all better and adjust when the tone arm sets down on the record. The arm will keep cycling also and may need more cleaning. My other problem is the pin you had so much trouble aligning. The rubber cover is in pieces. So I guess piece of wire insulation will do if I can find that size. Kinda like the Dual turntables and their Steuerpimpel ..LOL!
It's very good master👍
Thanks a lot!
Muchas gracias por este video, una joya de CZcams, ahora podré reparar mi Pioneer PL4. Saludos desde Colombia.
thank you so much for this video, it helped me so much to repair my bad 45 rpm, I repaired it thanks to you, thank you
You're very welcome. Glad it helped!
@@litzdog911 I really thank you so much you don't know how much you have helped me, without your video I could never have repaired it for this I'm really very grateful and I thank you very much again
Thanks Jim. I followed your tutorial when my PL-4 was running too slow and after some deoxit and use of the adjustment screws I was able to get the 33 and 45 almost dead on!
a tip : watch series on instaflixxer. Me and my gf have been using them for watching lots of of movies lately.
@Lane Salvatore Yea, have been using InstaFlixxer for since november myself =)
mine is the PL 4 and the speed is just too much is running like hell , so right now i am doing the work you did hope it get fixed, i will be back later : )
I did everything you said in your video and nothing, the turntable spinning too fast, I don't know what it could be? any ideas? Thank you so much
when I adjust down with the screwdriver the speed does nothing, the platter keeps turning at a very fast speed for a long period and then stops: (
Let me know if you find the fix for this!
also exchange c2 and c3
on the speed adjusting card for new ones
There are far better turntables out there, but this one is still my absolute favorite. I've owned 2 PL-5s and I have NEVER seen a dust cover that pristine.
love your video on this teardown and cleaning. I found the PL-5 a few years back and i think i even followed the guide you have there. Still had the same issue. The motor board actually comes out pretty easily so you can clean (or in my case replace) the fine adjustments for the motor, even replacing the caps for safe measure. I was still having problems with the speed fluctuations and removed the pitch control pot and speed switch. I opened up the speed pot and cleaned it out thoroughly and found that the remaining issue was the speed switch. I opened that up (not for the faint of heart) and found all the black oxidation is hiding in there. Put it all back together and it doesn't happen as much as it used to. I'm at the point where I think i just need to find a drop in replacement for that speed selector switch. Mine is actually made by ALPS. Any chance you know of a modern day drop in part for that?
Nice Video & Mp3 Song
Awesome video! I just wish there was a video to help repair my turntable. It’s possessed, time arm goes back and forth. Power light pulses.
I must have a bad motor? When my PL-5 came to me it rotated counter-clockwise and when it would run clockwise (it doesn’t move in that direction at all at the moment), it looked like about 120RPM. I followed your steps but no change. Start button doesn’t work either. If anyone has ever brought one with these symptoms back to life I’d love to hear how. Thank you in advance, and than you for posting your video!
Sure wish the internet was available when i was trying to resolve similar issues with my PL-4, I finally sacrificed it to the turntable gods and bought a new one. I liked the PL-4 better than the new Kenwood I had purchased.
Hello. Pretty much of a very good explained and detailed video. But however I need to get my hands on that transcript / instructions that you were reading from. Any idea of how to get it ? Can you send it to me ?
Sorry, I don't have a copy. You should be able to search for beej's post at Audiokarma.org
4:17 " Whats in there? Its a pretty good size." The tone arm rear shaft screw was removed with an Allen metric size 4.
I am getting a PL-4 tomorrow that may need me to refurb it. I have not taken apart a turntable since I was 10 or 12 (so 30+ years) But I repair other electronics as a hobbyist, so I should be good. I have seen that sort of strain relief on other electronics - they are pressure fit and a real pain!
Keep us posted on your progress!
I will! Thanks for the video, it will be a big help. I may even video my progress - I am currently working on some brewing videos to start my channel up and tech teardown videos for my work account, this may be a good thing to video as well! If I do, I will link and thank yours!
Well, I got it, and surprisingly the speed on it is pretty rock solid. The cut button and auto-return do not work, but that does not render it useless. Once I get a new cartridge for it, I am going to disassemble, inspect and clean everything - I will see about the mechanical issues then and keep you posted!
Awesome! Most likely the mechanism just needs some lube, or someone didn't reassemble it properly before.
Extremely helpful video. Haven't done mine yet. I have a pl 5 and a pl 250. The pl5 seems to gave speed issues. Is this electronics cleaner?
Deoxit is an electronics cleaner. D5 is recommended for switches and potentiometers, while F5 is recommended for fader controls where some extra lubrication is desired.
Hello thank you for the video it helps me a lot. I can't get the ring off the back wire, can you describe how you did it, please?
As I recall it took a fair bit of persuasion with a small screwdriver. There are a few other CZcams videos showing repairs on the PL4/5/7 models that might help you more.
Found PL-7 at garage sale for $5. I find this video after struggling getting the turntable seperated ugh..... 3 out of 4 buttons didn't work... the stop start spring piece was broke so bent some excess wire out from it and got it functioning.... speeds and repeat doesn't change hitting buttons - thats next project.... putting it back together to test is annoying though ...
That's a great find! Hope you're able to restore it. It's a great turntable.
@@litzdog911 Yeah I have stacks of turntables to fix - I need to learn how to restore these things. Unfortunatley they are rarely 'turn key' to flip. Using the money to get a Technics 1200 series. My old school personal table is a Bang & Olufsen
My ones the PL 430 the motor twitches and if i spin it it’ll run at 100 RPM, odd problem
Could anyone guide me to where I could get instructions for a PL-8? Every time I assemble it I get a different error.
You can download operating and service manual for the PL-8 here ..... www.vinylengine.com/library/pioneer/pl-8.shtml
Thanks! My PL-430 is up and running again for the cost of a can of deoxit. Now how are you with a Dual 1229?
Glad to help! You'll find lots of Dual 1229 videos on CZcams. I used to have a 1229, but gave it away. Now I regret that!
what cleaner did you use to spray down the speed controls? thanks
Deoxit D5
great video thanks. Do you have any videos on PL-25?
Sorry, no.
@@litzdog911 thnks
Turntables are not that complicated, but the tone arm and bearings are, this was never disassembled or serviced in this video.
True. The tonearm and bearings were fine, so no need to service them.
Thank you for your video. I just acquired a PL4, and I used your video to get inside. Unfortunately, my problem is that my table does not turn at all when plugged in and activated, and I am wondering if you have any thoughts on what could be causing that.
You’re welcome. Is the motor control board getting power? Is the motor itself getting power?
Very cool that you replied! I'll check when I get home, but what I recall from last night was that that area in which you would normally see the disk spinning lights up as your did in the video, but there is no spinning. I was thrilled to at least have the thing opened up, so I left it at that until later tonight. How would I check to see if the motor is getting power?
@@markkoch3012 You'll need to use a voltmeter. The AC setting will let you verify that the control board power supply is actually getting 120VAC power. Then check that the motor is getting DC power from the control board. If the motor is getting DC power when it should be spinning, then the motor is defective.
Awesome. I feel much better now. If I am going to continue to bring these as-is orphans home I am going need a voltmeter.
hey! is it possible to adjust the speed using a little screwdriver without remove everything?
Maybe. There should be an access hole on the bottom panel. The problem that many have is that the speed adjustment pot gets dirty/corroded and needs to be cleaned with something like DeOxit, and that would require removing the table from the bottom panel.
@@litzdog911 thanks for you answer!
What did you use for cleaner?
DeOxit D5 Cleaner
@@litzdog911 thank you
Algo muy importante.... No dijiste que lleva un tornillo bajo el contrapeso del brazo. por lo demás muchas gracias.
No entendi muy bien lo de la posicion del pin del brazo , tengo el mismo problema con este equipo la velocidad en 33 rpm varia
Last year I purchased a pioneer pl 7 turntable works really good except for one day the Quartz light went off and then it wouldn't play anymore it just went dead I need help!!
Sounds like a power supply issue. Do you have the schematic? Can you check the voltages?
You can download the PL-7 service manual from here .... www.vinylengine.com/library/pioneer/pl-7.shtml
@@litzdog911 no I don't have a schematic I'm not too good with that but I'd like to get it running again it played really well
@@litzdog911 okay Jim thank you I'll download it have a happy New Year
@@danieldehart7835 Hope you can get it working again!

So you don't have to lubricate the spindle ?
It didn't need lubrication.
@@litzdog911 its over 30 years old tho why not do it?
@@rosevillereaper9230 Didn't really think it was necessary. Table turned freely. Of course, you can lube if you want.
@@litzdog911Thanks for making this video by the way its very helpful . I don't see anywhere to drop the oil though. Do i have to take the cover on the spindle off?
@@rosevillereaper9230 You would need to remove the platter and spindle to lubricate. Be sure to download the service manual to show how to access.
