Technics SP-10 TT motor capacitors?

My hope is that it will meet factory specs, and continue to do so for the next 20 years. My table takes a bit to stabilize at 78rpm and I'm hoping that gets better. I'm getting up to speed on the service manual and the troubleshooting tree. My guess is that I'd see something a bit out of tolerance now if I checked with a scope, but I'm going to go ahead and do the caps as I do with all old equipment. I've seen too many old guitar amps with real leaky caps to doubt the fact that they will deteriorate after 20+ years. It would be an injustice (in my mind) to not take care of this classic machine as best I can. I have all I need to do this myself, so no big burden, and I enjoy it. You are asking a fair question and I appreciate the dialog.

I've wondered the same thing about plinth or no plinth.

SH-10E recap. Sorry, didn't really answer your direct question. Since it was a filter cap in a power supply, I have no doubt that I would have seen less noise on the output rail after cap replacement, to say the least. I didn't check though, cuz I've seen this often and I understand this circuit. I don't profess to understand the servo contol circuit, but I understand leaky caps.

Dear Strathorncat: Thank you for the info and yes I agree that it would be an injustice to not take care about.

My questions are mainly because my mind SP-10s whole project that I posted and I want to know if it will be worth the tremendous effort that could take the project, like I say is almost a re-design and build an almost new TT : sounds easy but it is not.

Anyway I think that this kind of dialog between so many Sp-10 lovers are really learning and enrich our own targets on the subject.

Regards and enjoy the music.

Well said, and I look forward to learning more. I'm just getting started with my table. Thanks!

Raul, I think you have the completely wrong idea in this rare case. For me, the reason to change the electrolytic caps in ANY device that has been sitting on a shelf for 20 years is simply to avoid a failure that could damage other, much more irreplaceable parts, NOT to make the turntable "sound" better in any way. If you read what I wrote, I did say that for a unit that has been in constant or intermittent service all along, probably this is less of a risk. Further, forget what I may think, Bill Thalmann agreed. He spends his days fixing broken electronics. Also, he did not solicit the work; he is snowed under with repair jobs. He had/has no ulterior motive whatever.

Having vented on that subject, I admit there ARE some sp10 users who think it is necessary to install Black Gate electrolytics in the PS, for reasons you suggest. I used Panasonics that cost less than a buck apiece in most cases.
