In Reply to: This is a bunch of B.S. nonsense.... posted by crooner on March 22, 2017 at 12:11:07:
Crooner,55 mA. at 440 VDC P-K ( amp uses fixed bias as I recall ) is 24.2 Watts dissipation of the EL-34. Looking up Mullard data sheets, they list 25 Watts as the EL-34's Maximum plate dissipation, in pentode mode.
If my math is correct 24.2 Watts is 96.8 percent of Maximum. Can we truly call that conservative operation ??
