TEAC 80-8 Repair Help?

[larrykohling]

Hey forum folks--

I've got a TEAC 80-8 with two issues:

1) a power transformer that buzzes, both at rest, and more loudly when the transport functions (play, rewind, etc.) are engaged, and 2) a capstan that comes loose too easily (I've disassembled and reassembled the capstan assembly probably four times at this point--every time, it's plumb and functioning properly, and then the slightest bump causes it to come loose).

I'm a newbie to tape deck repair--I used to have a really great tech, but I've moved to a city without any reel-to-reel competent technicians so any and all suggestions are most welcome.

For Power transformers that Buzz my solution is to remove it from the unit and dip it in Varnish.
I Dip it in a bowl with varnish and let it dry, then do the same procedure 2 more times.
The varnish impregnations solves the buzz

That could be a sign of a power supply fault, check all diodes in the power supply, running sections on a dummy load if necessary.
