I just got a mail from a SB1000 owner who gets the normal 750 -900 watts out
with his old used tube. But wíth two different new EIMAC tubes he only gets
around 200 -250 watts out and both tubes tubes get red. To me it is a
parasite suppressor that changed from original value and now with new tubes
with higher gain at VHF the linear is parasiting. Right? I am not sure, but
I think he said the ceramic switch needs replacing and he tried to get a
replacement from Tom? A burned switch is "normal" in a SB1000 that has
parasites if I remember right in earlier SB 1000 discussions on the net.. I
know Rich knows a lot of this fenomen, dont you?
Any clue? What to do?
