Does anyone have the specs for the current on the heaters and the HT side?

Thanks,

Brian

The heaters do not hook to HT!
How many power tubes? 1.5 amp heater for EACH tube, that is 6 amps total in 4 output tubes
How many preamp tubes? 3 tubes at 35 ma each = 105 ma
Now add all the loads together. 6.1 Amps X 6.3 V = 38.43VA
The secondary heater current rating must be 39 VA (6.1 amps) or higher. This is NOT the HT rating! The HT is HIGH voltage, the heater is LOW voltage.
OK try not to confuse the two. :thumbsup:
