[R-390] Gain Drift

[dog]

Larry,

If I disconnect tb102 3,4, the agc rectifier still works but doesn't 
send agc to the RF/IF tubes. What does grounding tb102-4 do? I know it 
grounds the agc line, but I guess that puts full gain on all the agc 
tubes? And measuring pin 3 tells me if the agc voltage is varying with 
constant gain tubes in the RF/IF? Seems to me if I have varying voltage 
on tb102-3 with no agc action there's something wrong in the agc 
circuit. I'll try it.

I have a question about the list operation. I see some people send 
messages to  my email. Some to both the email and list. But I when 
they're sent to both I only get messages from the person, not the list. 
Also confused about sending. I usually just send to the list or should I 
reply to all? It seems then people would be getting 2 of the same 
messages? Confused as usual. Using Thunderbird.
