Hi all,
I am assembling my crack, it's not quite finished. Before connecting the B+ to the amp, I thought I'd check it first to be sure it's wired correctly. It seems to be but I get 235 VDC at the output (across the 270k resistor), I expected 170 VDC.
The transformer secondaries before wiring measured 155VAC.
Am I good to go? Will the 235 VDC draw down to 170 VDC with the tube load? Thanks.
