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
