I did a DUMB THING... Philco 39-7 radio

Found this little radio in a pile of trash. All the tubes are in it.

I looked over the chassis a little bit and noticed the 2 electrolytics in the power supply were shot. Replaced them with new ones under the chassis.

Brought it up on my variac. At around 80 volts, I started hearing noise and hum when I touched the cap on the detector. Then, smoke... from the power transformer. Turned it off fast.

Idiot me didnt notice that the wires on the power transformer were no longer insulated at all. Thanks, Philco, for the rubber insulation.

This weekend, I hope to pull the power transformer, open it up to separate the wires, and see if it is actually fried.

This is not my month for power transformers!
