Thanks to all who responded off list.
There were multiple ( additive ) problems with this old transmitter
in addition to various metering positions not indicating ... including
FWD power. ( sigh )
Generic NTE / ECG transistors were replaced with proper value and gain
transistors and we found that most of the small signal capacitors were
dried out or at 1/4 value.
Dirty can't convey the condition of 20 years in an unfiltered environment.
How 12 KV could survive ? .......... I just shake my head.
Anyhow... It's been kinda fun going back and re-educating myself on these
old classics.
