Hi Tom I am having the same sort of problem here, except it is on 80 meters only that I am having the problem. My SB 200 is fine to my TS-450SAT on the 40-10 meters, but on 80 meters, it has a super

Hi all I had a FL-2100B amp and the way they said to tune the input is to disconnect the high voltage lead from the transformer and tune the input that way. Is there a site that shows, or what is the

Hi All I am getting a new set of tubes for my SB-200. I assume that after I put them in, I will have to retune the input. Where can I find a non-conductive allen wrench to adjust the slugs in the coi

Good advice!! I have always found once smoke starts pouring out of the amp, it is easy to see what the problem is. Kinda like the smoke they put in all those solid state parts. 73 Tom W7WHY _________

Hi Lou I guess I didn't explain it right. What I meant is that after it cools down, I can manually reset the breaker. If I push on it right after it trips, it won't reset. Actually, after a while I c
