I run my '78 (with the original tubes) on RTTY at about 500W. Even at
that level, the air coming out of the chimney holes gets fairly warm. I
haven't measured it yet.
One of the main reasons I got it was that I judged my existing linear (
30L-1 ) incapable of doing RTTY at any power level whatsoever. And I
had broken an SBE SB2-LA ( one shorted grid ) on RTTY.
I suspect that contesting is actually easier on the equipment than
ragchewing, because the exchanges are so short.
