Philco 46-431
#3

Thanks

I generally rebuild the entire power supply on a radio in this shape replacing all the resistors and caps.  I definately won't plug it in until things are rebuilt and checked out.
I suspect this radio will need lots of replacement capacitors from the looks of the ones in it.

This radio has a combo dual .01uF  capacitor/terminal strip for the incoming AC line. I'll probably remove it and replace the capacitors on a terminal strip, unless I am told this is a bad idea or someone has a better idea.

If the power supply dual electrolytic cap is easily removed, I'll probably gut it and stuff it with new caps. Replacement caps will be much smaller. I may increase the value of these if the rectifier tube can stand the increase. I haven't looked at the tube  data yet.
