Hi All,
Posted here before about this but have a follow up question.
I've been told that the problem is not the tuned input ckt. but the
811 tubes. I fully admit that I'm not an expert on RF Amps, BUT it has
good output on all bands except 20M. The tuned input on 20M will not go
below 4 or 5 : 1 , all other inputs go to 1:1. I kind of think that if
the problem is isolated to just the 20M tuned input that the logical
"suspect" is one of the caps in the tuned input ckt. or am I incorrect
and the 811's are the suspect? I "do realize" that the 811's are easier
to change out, but it still doesn't compute in my ole brain.
Thanks for everyone's feedback on this.
