I have an old Vector Research VRX 9100 receiver that will (usually)not
play the left channel until you really turn it up. Once you do, you
can back the volume down to a much lower level and it will work fine.
Sometimes I turn it on and it's fine out of the chute. I assumed that
the protection relay was causing the problem so I opened a little
access port in the side of it since it was too well sealed to get open
and cleaned up the contacts for that side. Still same problem. I can
actually get in there with a pick and screw around with the contacts
when it doing this and still no dice. Thats exhausts this rookie's
limited diagnostic ability. I assume it could be an output transistor
but i don't know if they fail this way.
Thanks,
Robb
