I want to add an "Attaboy LON!" here because I personally own one of his
SB220 mod jobs and it is a pure pleasure to operate. I just wish that I
could use the SSB side of the switch but without replacing the bank of
capacitors with a set of 10, then reconfigurating the meter - I am stuck with
what I have.
and that is, an amp that is permanently set in a slightly weak SSB position
by using the CW/Tune switch. iow, in that position with the Peter Dahl
transformer and all the mods, it does up to 1kw. flip on the SSB switch and
it hums and buzzes and the meters peg.
Really need to take it back to Lon but it is too heavy and Lon's lighthouse
stairs are just too much for my knees to take.<G>
But then, who needs more than a KW anyway?? if you do, go get a bigger amp.
Thanks Lon for an amp I have thoroughly enjoyed for about 2 yrs now. Super
job.! Just wish I could find some like mine (well, with a properly operating
SSB switch<G>) for all the members of Army MARS in Texas. Then maybe we
could hear each other.. hi!
