I replaced the three main PS caps and measured voltages last night and my Apache showed the following in the AM Mode:

F = 3650 kHz
Primary Voltage = 110V

PO - 110W,
IPF - 260 mA,
HV - 713 Volts (THIS IS WITH ONE 5R4 which is all I had at present),
IGF - 3 mA
IM(resting) - 45 mA

This unit has the Svetlana EL34 Modulator tubes.
