O.k. here's the amp:

Uses FOUR 6973 power tubes that routinely cost $35+ a tube....$140 for a quad. OUCH.
Well, I can buy THESE NOS USA made for $3 a piece. very close but lower plate voltage rating. TEN for the cost of just one tube!

Think they can handle it? How would I bias with no cathode resistors? Should I reduce the plate voltages with a different rectifier tube? Am I dreaming?
