There has to be something said here for the fact that Carl (KM1H) and myself
have very successfully converted SB-200's to 6 meters, and getting 700-800
watts out of them depending on how "hot" the whole conversion works out. I
don't think anything is specific, but to simply say a 572 should not work on
6
meters is hogwash. They may rate it to 30mhz, but they do work at 50mhz.
If I was to have to answer the question "WHY", I guess something has to be
said for the fact that we are using a SINGLE band tank circuit, which holds
the
stray "C" and "L" to a minimum ie..no long leads going to a tank circuit far
away from the load and tune caps. This is where instability can arise. SO
in a nutshell I'd say WE make them work because we make them a single band
amp. The parameters of the tube are as good or better than what you see on 80
meters. Does this answer your question??????????????????? Lou W1QJ
