[Amps] Supply question

[Gary Schafer]

With 3500 volts @ 890 watts PEP out per tube 3rd order IM products are -40
db with respect to one of two tones. That's -46 db the way radio
manufacturers spec IM. Pretty darn good!
At 2500 volts 3rd order IM is -33db. Per Eimac spec sheet. Much better than
most radios today.
