Every now and then I haul out my SL-1500 to digitize some more of my vinyl. I've had a speed drift problem for quite some time and thought it might be a bad component. After finding this video and performing the procedure, it's now rock steady! Thank you very much for making this video.
You just saved me at least $250 to replace my dad's SL-1510. The fix worked and you explained it perfectly. Absolutely fantastic. Thank you.
Thanks so much for the Awesome video!!! This procedure worked like a champ on my Technics SL-1350. It was running too slow on 33 1/3 rpm. I cleaned all the pots as shown in your video, and now she runs perfectly, and the pitch adjustments work exactly as intended! Thanks again!
I know this is an old video, this really helped me figure out what VR1 and VR2 were for and that the third pot not labelled on my circuit board was the pot for 78 rpm I was looking for. Now all three speeds work great! Thanks!
Just used this to fix a Technics SL-3200 that had been in storage for 20+ years. Speed was erratic before, then followed the directions here exactly. Now it runs perfectly smooth. Thanks - you just saved me a repair bill.
I saw this video a few years ago and I used the CRC cleaner and it helped somewhat. I have a Sl 1500 that is from the 70's that I bought used about 25 yrs ago. It had the same problem from day one. Maybe that's why I got it cheap. Yesterday I watched this video again as a refresher. I took it apart again but used Deoxit D5 this time and now its steady as a rock.
Thanks for this video. Now I can enjoy my albums again.
What you want to use is the Deoxit F5 rather than CRC or D5.
This worked great on a Technics SL-3300, fixed an unusable turn table into one that is rock steady.
Thanks for sharing this video in such great detail!
Just scored an SL-1800 for $12 at the GoodWill 2nd hand.
Speed was real dodgy, but the contact cleaner in the pots did the trick!
Thanks to you, I'm chillin' to Shuggie Otis now, got dub to rock to techno to soul waiting in the crate!
Cheers
I have a sl1500 that I just bought and the speed was changing constantly and the control speeds would wander constantly. I watched this video and went through every step that you mentioned and I now have full control of the speeds and your process worked perfectly!! thank you for this video sir!!!
I've had my Technics SL-1500 for about 45 years. Scary thought. Have never done any maintenance on it, but have a project I need it for. Noticed that the speed was quite unstable. Found this excellent UA-cam video and it is now rock solid stable. Only difficulty I encountered was one screw on the circuit board. Fortunately, letting it soak in Liquid Wrench for 5 minutes finally allowed me to get it to budge. All done, working great - thank you!
Exactly same turntable and a problem. Now working like a dream. Thanks a lot mate! I owe you a beer.
Bought my SL-23 at a garage sale, thought it was completely dead. After belt was replaced, fix worked perfectly!!!! Thank you so very much, sounds way better than my old one :)
As others have said this works brilliantly. 15 years in storage (after speed issues) and the SL150 is now going like new, and applied same techniques to crackling volume on amp and it did the same great job. Thanks for the great video.
I just used this procedure to fix my sl-1300 (purchased in 1976) and it worked like a charm. Thanks very much!
My Technics SL-B3 was doing the same stripped it down & did very similar service ,now working better than ever , wish i had seen this video before i did it , great video btw
This worked a treat on my technics sl-b22- a bit different inside but my player is running at the right speed again. I am delighted with this, was considering buying a new deck. Is great to be playing my old records again. Thanks so much for uploading. Brilliant!
I haven't tested it yet but thank you, thank you, thank you for your concise and yet detailed video. After many years of non-use I noticed a small slowing down of the turntable and I am confident this fix will get me back on track. I salute you, sir!
Thank God for FF and volume control. Thanks btw, Space Boy! Lol...in all seriousness, I realize this vid is 10 years old and I greatly appreciate you making it!!!
THANK-YOU!
I did all that, and my SL-1300 now works as new!
Only thing; I use CRC Lubricant only, as I’ve experienced the cleaner formula too harsh on some potentiometers in guitars. CRC 2-26 Lube has never disappointed me.
Thank you TheRecordReporter. I followed what you outlined in this video, step by step and voila.....it works! The guy I brought this from sold it to me for a bill but what intrigued me to buy this is that this Technics SL-1300 came with the Grado Black Stylus & this cartridge and needle cost, in some cases, more than the turntable alone.Thanks again & God Bless......greatly appreciate you sharing this video!
Picking up a gift of a SL1800 from a friend next week. Your video is very good! Thanks.
Excellent you helped me out immensely, I’ve just done mine this afternoon and she’s holding speed perfect right now thank you 🙏🏻
Worked for me on a Fischer direct drive turntable that I almost threw out. Many thanks as this works perfect now! I have had this since 1980 and now many more years to come.
Congratulations on that great Goodwill turntable find! Glad to hear you were able to get it back in action.
Thank you for your tutorial video!! Applied this very same process to my '76 Sony PS-3300 Direct Drive and it is now working beautifully. It had previously become unusable and I thought it might be be a more extensive problem, like aging filter caps in the speed control circuit. It was simply spraying out the speed related potentiometers and switch, just as this video instructs.
Really did not want to part with this turntable due to sentimental value and it's arguably a better unit than most current mid-level consumer grade models, without stepping up into audiophile range. Thanks for making it happen!
Superb video, very clear and straight-forward: Thank you! I will try the steps shown on my SL-5200, which has a slide switch for 33/45 and a single rotating pot for adjusting speed when the quartz lock is off. I bought this turntable new in 1978 or 1979 and it has operated flawlessly until now, when it has developed a "hiccup"-like variation in speed. Don't let anyone tell you Technics turntables are unreliable!
Thank you so much for this video. I just purchased a used SL-23 and not only managed to fix my speeds, but now my 45rpm works GREAT!
Worked like a charm. I have a SL-3300. Thanks for posting, I was about to give up on my old friend. I like your blog too!
Great video dude!
I'll be making a little money on repairing turntables, but I got a SL 1500 with the same speed problem as yours, now I know what to do!
Thanks for helping me out, now I can buy a new amplifier at the end of the summer! :D
Knowledge = power!
one of the best DIYer videos ive seen. gonna give it a shot on my Technics
+micky d Thanks and good luck!
Wow -- what a PERFECT instructional video! I have a Technics 1600, and the symptoms are EXACTLY the same. Can't wait to investigate it armed with this knowledge. Thanks so much! Now I just gotta find QD Electronic cleaner, and some motor oil, too.
If the author still cares about the comment section of this video, thank you so much! I bought a b-stock Lenco L-85 (the new model), which was playing fine for the first couple of minutes, until I slightly turned up the 33 1/3 speed screw. It suddenly stopped maintaining a stable tempo. I started filling out the refund form when I found your video and thought 'what the hell', and sprayed some white grease onto the adjustment screw (potentiometers built into the motor), and it finally started playing at the right speed. Thank you!
Thanks for the comment! Glad the video was helpful to you.
Nice video, this also illustrates the method for the earlier Technics turntables, ie.SL110, SL120 etc. One small point you didn't mention is when making the final speed adjustments check that the main speed control knobs are in the centre of their rotation then adjust the potentiometers on the circuit board for perfect speed.
Thanks so much for putting these instructions up, I really appreciate it! I inherited my older brother's 1974 SL-1300 and although it worked okay, the 45rpm speed would always drift around when swapping back from 33.3. You had to adjust it every single time and there was hardly any range left on the dial. Now all the pots are much smoother to turn (I used a cleaner with lube in it), the spindle has been oiled for the first time in 43 years, the speeds are stable, and I now know what the two dials under the platter are for ;^)
My kids are now spinning records on a deck that's been in the family for three of their lifetimes, pretty cool.
Great! Glad to know the video helped. Thanks for the comment.
Great video. No talk talk, straight to the action.
@The911nut You're welcome! Glad to hear you were able to get your turntable back in action!
Hi. Thanks for this informative video. I have an Onkyo CP-1011F Belt Drive turntable and I was having the same problem with unstable speeds for 33 1/3 and 45 rpm. After changing the belt, lubing up the platter spindle and a lot of weak solders on the circuit boards, the speeds had gotten better but would change on their own after a while. Your technique with contact cleaner on the pots and the pitch control, now the turntable sounds like brand new. Thanks again.
Worked perfectly in my Telefunken TS-950.( Version of the Technics SL1900). Thanks.
Appreciate your video. Just cleaned my SL 1300 and it works flawlessly. Wish I had done it sooner.
I'm setting up my old Rotel system, with ADC Sound Shaper, Akai tape deck and of course my SL23 turntable. I picked up a well used audio cabinet yesterday, repainted it and put a new back on it. It's going to be awesome!
It worked! First I tested the components and even replaced the servo uProcessor chip to no avail. The VOM readings and scope waveforms were all over the place. Finally I sprayed the contacts with CRC contact cleaner from Lowes and it works perfectly! Sometimes its the simply solution!
Thank you for this very cogent video. I followed the explicit instructions and fixed mine in about 20 minutes.
Glad it helped! Thanks for the comment.
@AudreyElizabethB That's great! Thanks for the feedback and for checking out the blog. Glad to hear you liked it!
Thanks man, this is EXACTLY what I've been looking for!
Thanks ! It's perfectly stable, now. And the tuning of the speed is very precise :)
great guide, quick, easy and effective!
Awesome, so very happy to have my turntable working again! You rock and thanks for posting!!
Glad it helped, thanks for the comment!
@chris2crazzy Thanks for checking out the video. Good luck finding a new knob for your SL-1410.
Thank you! Very informative and easy instructions to follow.
Thx for the tutorial. Just used your procedure on the SL 1500 without any problems, it was really bad before and now it sounds great. All the screws on the bottom of the player need to be removed btw. Made use of Deoxit Fader Lube F5 on pots and Kontakt 60 on the mode selector.
fixed a sl-83 with this video, thanks!
Another successful operation! Glad to hear it!
I’d just like to say what a well done video👌
Thank you very much!
I finally got my turn table working thanks to this 🙌👌👍
This was exactly what i needed to see. Thank you so much for the fantastic video. bravo.
Do you have videos on cleaning knob control on Pioneer SX1050 and SX750 receiver? Thx
Thanks, you make it look very easy, but would you recommend it to someone with not so much technical experience?
This method works! I did it on my Mitsubishi with only 2 pitch pots and rpm switch (no condensers).Spray, twist knob, repeat.
watched the video and it worked great on my sl-1300, thanks. i have another issue now, the tonearm won't return at the end of the record. is there an adjustment for that?
thanks for the quick replies. again, a very easy-to-follow video with excellent editing.
Thanks for an awesome video. Exactly what I needed. Will perform procedure tonight on my SL-1800. Muchos gracias!
Thanks man, this worked on my sl-1510
I tried this out on my sl-b200 and although the schematics are a little different, I cleaned the exact same components and it works much better
You're welcome! Glad to hear it worked for you!
I just succeeded in fixing the speed of my table! Thank you so much!
Thank you for your tutorial video......it's very useful.
To my question, what type of Technics turntable do you utilize in this video ? it looks like SL-1700 but has two knobs of pitch control.
Secondly, how to clean dots surrounding the platter ?
Great! Glad to hear it did work out for you. Thanks for the reply!
will this work for my sl-b205 technics turntable?
Right brother! Time to get the 1974 SL 1300 out and perform this procedure. Thanks for the vid! Peace
Hi, thanks for the comment. I haven't tried it on a belt-drive yet, but if yours has a speed adjustment control and/or speed selector switch, I do think there's a good chance this method can help. If the problem persists, even after cleaning the pots/switches, I'd try cleaning the belt and pulleys with some alcohol in case the belt is slipping due to residue. Don't touch the cleaned belt/pulley surfaces with your fingers. Lubricate the center shaft bearing. Replace belt if all else fails.
I'm looking for a good replacement cartridge for my SL 1500, any good recommendations?
And headshells!
My platter was stuck on there pretty good at first too. You just have to lock your thumbs in the two opposing holes and evenly push with your fingers on the base until it comes off. Maybe rotate the platter back and forth a little at the same time.
If you haven't seen it already, check out my blog article for some more info (link is in video description)
...there's some extra stuff written there about lubricants, cleaning sprays and more.
Good luck!
Thanks! This worked like a charm!
I have exatctly the same turnable tabel but the SL-1700
witch one it'S better ?
Thanks! Glad this worked on your turntable!
Great video! I have a belt drive turntable which has the same type of problem. Do you think it can be fixed with your method? Thank you!
Thanks for the tutorial. I used the cleaner on my turntable Sony PS-212A, and it fixed the 45 rpm issue on it.
What would you suggest if this partially fixed it. Sometimes when starting up it plays perfect and the dot test passes, other times it runs slightly slow with the speed dial set as fast as it will go
I have technics sl-23 belt drive ,speed run too fast ,can you show how to fix it. Thanks
hola tengo una tornamesa technics 5300 problema cuando la enciendo el plato arranca a alta velocidad cual sera el problema
Thanks, it also worked for my SL-1500. Just to let you know, I've picked it up at a thrift store almost 20 years ago and this is the first time I had to do work on it. I went through all the steps and the result was not satisfactory and opened it up again went through the steps one more time. Viola!!!
+bonbonturc Great! Thanks for the comment.
Worked well on my sl 1300. Thanks
Great tutorial. thanks a lot. I'm hoping things are similar on my SL1200 MK1. I don't doubt everything stops when I try to separate the base, but I'm going to try it.
Thanks again.
Also, what type of oil do you recommend on the motor shaft?
Oh yeah! What do you use for oil? The stuff fro KAB usa, or something else?
Great video, works for the SL1500 too, thanks
Great! Thanks for the comment.
great video,very helpful.
Great Video! Will this also work on a Technics SL-220. It is a belt drive turntable from the late 70's. Excellent shape, just has unstable speed at times. Thanks.
@mmay519 You're welcome. Glad to know it helped! Thanks for taking time to comment!
Thanks a lot, it works for me
And the music was great too xd
I have the same SL 1300 but my problem is cueing set down point and return. When I hit start the tone arm goes all the way to the spindle and comes back and shuts off. Any idea?
Thanks! This worked perfectly on my SL-B1!
Good news! Thanks for the comment.
You're welcome. Glad to hear it. Thanks a lot for the comment!
Yes, you are right, a contact cleaner with lubricant would be preferable to what I am seen using in the video. I actually mentioned something about that in the blog article. Thanks for the comment.
Many thanks, it really works on a SL 1500, but with lubricant pot !!
Thank you very much I've got a Pioneer direct drive tomorrow I am going to service it like you did I'm pretty sure it will be the same sort of stuff.👍🎼
Thanks for that. Good to have some pre knowledge before I open my sl1800.
Thank you for the advice. I will try your method!
I have just bought a used mint condition sl1300, the 33 rpm holds like a rock but the 45 is at the wrong speed according to the strobe and will not settle at the correct speed, will this procedure cure it or is it something else, thing is i dont own any 45's so should I just leave it be ?
I have the same turntable as in this video, but I can't seem to get the platter off. Is there some trick to it? Also, can you recommend a good lubricant?
