I am in need of some help.
I have a Philco Model 84 (I think model b) that I have decided to restore. All of the leads attached to the power transformer are crusty and the shielding is breaking. I removed the transformer and plan to re-sleeve them. I gathered up some test equipment, isolation transformer, variac, and I built a dim bulb tester.
Now the problem. This transformer has 9 leads. The schematic I have for the radio shows the transformer should have 10 leads, two secondaries with a center tap on each and the third without. I found another schematic for a 37-84 it shows only 9 leads but with different tubes. I found on ebay someone selling a transformer with the same model number (different year) but it has 3 leads for the primary where I only have two.
All leads on mine ohm out so no shorts. I found the center tap for one of the secondary windings. I tested up to 115 volts and I see 5v on one winding, 270v on another and 3 on another.
Does anyone have any data (expected voltage, ohms etc) for a 32-7180N transformer. My date code is 6-35
Thanks
(fyi I am new to this)
