Power transformer in a 12 volt/25 volt radio?
#13

Both transformers you have listed are 25V only. How are  you going to obtain the high V output for the  rectifier?

Well, that was the issue. I think I would have to run TWO transformers: one that supplied HV and 6.3 filament, and another that supplied 25VCT, so I could cover all filament voltages...that is unless I could stumble on the exact transformer that Stewart Warner had made for this set. 

I have a Philco 77 chassis that had a burned out HV secondary in the original but the filament secondary. The solution the technician from the 30s used was to bolt in a second power transformer from another Philco to provide the HV for the set and power it from the mains. I have no idea how well it worked. I used the chassis for parts.

That is why I've been thinking about the 6 volt solution.
