[R-390] Gain drift

[dog]

Well, maybe I've found the problem. Took shield off T502 and found some 
funky solder joints. Re-did them and now I don't seem to have that 
drifting problem. But now I've got a loud white noise that comes and 
goes. I'm feeding signal into the IF and listening on the diode load, 
and there is no indication on the carrier meter or the milivoltmeter 
that anything is changing, I tried all the IF amp tubes to no avail, but 
it's probably in the detector or maybe limiter, don't know where else it 
could be.

Getting closer. Gotta go mow now.
