Have you checked R60 & R216 and the voltage on
pin 2 of V4? I bet that +5volts is a bit higher?
That higher voltage on your AGC tube pin 7
of V6, 20V is higher because it's coming
from the plate of V4, so it's to be expected.
with the antenna not connected, no signal
do you still get -5v on V4 pin 7? If yes, you
might just have a noise source being
rectified through the V det. Until you
can figure out that -5V I'm not entirely
sure you have an AGC problem.
But the no Snow condition
certainly points that way.
It's a Conundrum for
sure.
