I've had a play with the Variac, and if I have the transformer putting out 271-275V, this runs the 6V6GTA anode at high but safe 308-313V. The circuit is supposed to measure 342V at the anode. Can I use Resistors to achieve this reduction safely, as discussed above? The transformer is barely warm after 30 minutes of playing. The output current measures 0.015A when the meter is put in series between the transformer output and rectifier valve.
Hope this makes sense.
Cheers from Bill.
