Sorry if my question was misleading. The data that I am missing and
cannot find is the operating characteristics of Taylor 572B's. You have
all seen the curves. I do not want to read plate voltage and plate
current off the front panel meter that are already affected by an
improperly designed tank circuit and bad tubes. I am well aware of the
handbook formulas. Thanks & 73, Tim

I assume from the original question that the desired class
of operation is AB-2, or B.
If that is the case, the formula is:
Anode Voltage
_____________
Anode Amps X 1.8
(Several values for the "K" factor have been published, but
this is the one Eimac uses)
It makes no difference what tube or tubes you are using;
just how you plan to run them.
