JVC tt-101 repair


Got a JVC QL-10 with a 120V TT-101. Speed is wonky. Sometimes plays fine, sometimes spins a 1000 RPM, somtimes runs forward & then backward. Could use some help.

Hello group!
i just inherited a:

JVC QL-10 TT-101
Victor Company of Japan Ltd plinth,
120v 60hz.
And it has a Lustre GST-801 tonearm.

I plugged it in and it ran perfect for about 10 minutes (33.33)
After that, it just took off to over 60rpms and it won’t slow down.
it was my uncles, he bought it new in the 70s.
it hasn’t been use for many years.
anyone else had this problem?
Thank you.

anyone else had this problem?

In many we have had very very similar problems.
Someone has solved them, others (like me) are still working.

Look this...

As I posted on your Audiokarma thread, 1st place to start is with the double sided PC board eyelits. Several have stated this is an issue with this table. Mine had the same speed fast issue. Though it took 3 tries with the eyelits with 3 separate speed issues ( running fast, intermittent cogging between 33.32 & 33.34 and stopping issue), it now runs as it should. If you don’t feel confident to try it, read as much as you can, get with a competent repair shop in your area and discus it. Probably can take care of the speed issues.
