I was reading the Bill Orr handbook and on his section about amplifiers he  
says.....A properly designed grounded grid amplifier should produce 2 to 2.5  
times the plate dissapation of the tube  in output.  He did not put  any 
limitations on the statement as to IMD or anything like that.  He did  not say if 
the tubes ratings would be surpassed (I am sure they would), but I  think what 
he was saying is that the tube should continue to make power to 2 to  2.5 times 
it's dissapation before it would not make any more power and flatten  out.
 
Upon speaking with an amp "Guru" about this subject, he procalimed that  Bill 
Orr was a "QUACK".  The basis of his claim was that he was never able  to 
build an amplifier that obtained that kind of results.
What say you?  Lou W1QJ
