Hi Brad,
I'd be interested in hearing how the replacement TV transformer worked out for you. Were you able to get the proper biasing voltages? For some reason, I'm still hung up on the asymmetrical center tap. The schematic shows 85 ohms from one HV leg to the tap and the other HV leg shows 75 ohms. I figure there must be some reason Philco did this. So far, I haven't found any information on this type of transformer. I tried to model it in LTSpice but can't figure out how to set it up properly.
Thanks,
Rich
