Ed,
I'd appreciate that. I'm not sure how close these chassis's are but any
information and/or schematic on the tuner would help.
Thanks,

From you description, I assume that this is a tuner related problem?
I have seen the osc crystal and the tunning IC insde the the tuner area
give troubles like that, Most recently the IC tunning voltage drift has
been
more the culpret than the crystal.
