Steve,
Another place to look, check V16, (12AU7), and the capacitors associated
with the carrier oscillator.  Possibly  something here is temperature
sensitive, and is pulling the carrier xtal off freq.   If this is happening,
the carrier may be too far down the slope of the filter, and that might
result in the condition you describe.  When out of the cabinet, it may run
cooler, and not shift the xtal frequency as far, allowing more output.  Just
a thought, and worth about $0.02.  so-
