Since David was kind enough to post the proper schematic, was hoping I could move over to my next question on this thread.
While waiting for an audio output transformer to arrive, started making checks on the power transformer. Found the center tapped
secondary to the plates of the rectifier open. No resistance across the the winding or from center tap to either side of the winding.
I've found a transformer made by Hammond the 270BX. Secondary outputs of 6.3 v 2A, 5v 2A. question is I'm not sure how to interpret
the data for the center tapped winding. It's listed as 550 VCT 57.5mA. Does 550 VCT mean 550 V across the coil if the center tap is unused.
Or does it mean 550 volts on either side of the center tap connected to B-. Plus not sure if the amperage ratings are correct either.
Or do I have different options altogether I'm not aware of.
Thanks
Tim
