I only use my 3K premier on 80 and 160M. When firing up the amp after not
using it for about 6 months, I was tuning up on 160M when I turned the tune
control off it's end stop, as I do about one a year!
After opening up the top panels and putting the tuning control back on the
track I turned the amp on and the main house breaker on the 220V line
immediately popped!
After resetting the circuit breaker the amp came on again without problem
but now the T/R switching does not work and the amp will not go into
transmit.
I measured across the relay control;RCA connector and get 30V.
When in idle (no drive) the following are meter readings:
HV approx 4500V SSB and 3700V CW
Grid 0ma
Plate 0ma (I would have expected something here)
I have little Amp troubleshooting experience (just some work on a SB-200
previously).
Any ideas where to start looking?
Thanks,
