OK, just what IS wrong with this picture?  I run 400 watts AM carrier regularly with my military T-368.
With the linear’s I do the same.  The amplifiers are running class B at an efficiency of 50% and thus dissipating
400 watts during carrier only and 800 watts on voice peaks both which values are well within he ratings of
a 3-1000Z.  Also please note that in my home-brew unit I’m still running the same tube I originally installed
almost 30 years ago.
