What's that, DOc?

You don't believe these old rigs could produce their advertoised 
800 watts p.e.p. output from a air fof 6KD6 tubes?
(grin)

Well, wait a minute - they advertised peak INPUT power back 
in those days, so that was probably only an average of about 
100-200 watts input, to meet their specifications...
