Hi All
My progress has stopped after recapping it but the AGC wasn't working.
I found that T503's secondary was open and R525 was cooked.. T503 and R525
were replaced and now my 390a has no receive not even IF hiss. I checked my
work many times..........can someone provide a .jpeg or two of the T503, L502
V504 area on the IF?
I can hear some RF gain noise when turned full. All tubes are fine. Did receive
before replacing T503 etc. The 390a sounds muted.
Thank you!
