Philco model 42-1012 power problem
#4

gvel Wrote:Hi,

schematic is here: http://www.nostalgiaair.org/PagesByModel...013494.pdf

The power transformer/rectifier in on the right, toward the bottom.

Pull the rectifier tube, if you plan on starting it up to check transformer voltages.
If the power transformer checks out OK, change electrolytics and line bypass caps then "fire" it up! Icon_biggrin The line bypass caps are part 101, 2 x .01 uF. The radio will work w/o the bypass caps, so if you don't have any, oh well.


I have power to the chassis block and nothing coming out of the trannie if I check on the rectifyer pins.
There are 2 yellow and 2 green wires coming from the tranny to the rectifyer.No juice on any of them.
I assume it is bad.
I can detect a color scheme on the tranny wires on some of the wires.Not real clear on others due to wax leakage from the tranny.
If I were to get a used transformer,what are the odds that I will be able to seee the wire colors?
Appreciate your help guy's
