Vintage DD turntables. Are we living dangerously?

Lew, I suggest that if you have or have access to an iPhone that you check out the Tesla app to see where the EMI is. You might not have a problem.

My intermittent speed problems on my Pioneer Exclusive P10 - racing up and down and failing finally became permanent.

Took the table into the tech and he said most probably changing all the caps would fix the issue. yesterday I got a call that the table was ready.

When picking up he said that replacing all the caps did not fix the problem. he searched the entire web and no schematics on the table. He eventually found it was a faulty IC from the 45rpm control that did not switch off and would distribute noise/interference to the 33 IC control.
these specific IC's had been long discontinued. So he studied a bit more and made his own! problem fixed.

the interesting this was that the tech had previously worked on Denon and Halcro's JVC DD's. Even thou they look similar from the outside, the internals and design's of all 3 were very different as was the number of parts, complexity etc etc.

I played it at home all last night and the speed sync's straight away and is playing beautiful music - fingers crossed it stays that was, but with the caps all changed on my 35 year old DD I have a fighting chance :-)

cheers

Downunder,

Great post, pleased you got that classic up and running. Perhaps your tech should make his substitute IC available to others.

Hi Albert

I have no technical ability, however I assume a really competent/talented technician would have the necessary skills to copy an entire IC, which is what he did.

Thanks to Halcro for recommending Chris Kimil, even thou he had replaced my Wilson tweeters. I did not realise that he fixed turntables.

I am even thinking now of having the tech replace all the 35 year old capacitors on my Exclusive P3?

Absolutely, I would do that.

Not only would new caps improve performance and reliability, it might avoid a failure that kills a hard to find part.
