1939 Philco table radio

[holmesuser01]

I've got a little table radio. It's got rubber insulation on the wiring. When I got it, I replaced all the capacitors without paying attention to the rubber covered wiring. I brought it up slowly on my variac, and was starting to hear AM broadcast noise, when I started hearing the 'putt-putt-putt' noise from the power transformer. I turned it off, and over the next few minutes, with power turned off, the transformer got almost untouchably warm.

What I'm asking is, do you think the transformer is ruined, offhand? I've begun disconnecting it so I can get at the rubber covered wires. When everything is separated, I would like to power it up and be so lucky that it might work.

It smelled hot, but there was never any smoke that I saw. Like I said, AM interstation noise was coming thru the speaker when I heard the noise start. There's a 2 amp fuse on the variac that didnt blow, and I had it running at around 90 volts at the time.

This is one of the radios that used the 6Z4 tube... I think... I'm not looking at it right now... the rectifier looks like the early 6X5GT tube inside.

I appreciate your comments. I hope that this little transformer is more robust than the stuff they make today.

I'll try to post the correct model number as soon as I can get to the radio.
