New Philco 41-225
#11

WWIIRadio, where did they put the toggle switch? Did they drill the cabinet to mount it, or was it on the chassis? I have a 41-280 with a toggle switch on the back of the chassis, so before I fixed it you had to reach behind the radio and feel around for the switch to turn it on. That was annoying.

I'm working on a 41-255 now. It's one that has a lot of miles on it. There are several screw holes drilled in the chassis where there aren't normally holes, maybe for modifications or repairs that have since been removed. Most of the tubes are replacements. The 41 and 84 tubes are not the ST type and are various brands other than Philco, so I conclude that it has been played, repaired, and tinkered with a lot.

Both the power switch and the output transformer were bad. I replaced the output transformer with a Hammond 125B. In retrospect, I think I'd use a 125C if I did it again because the "B" has six secondary wires, 4 of will be unused. I'll probably cut them off, but for now they are a nuisance. I think I'll probably use #1 and #3, but I don't want to cut them off until I have a chance to test that those are the best choice.

All the other 125 series transformers have solder lugs for the secondaries, which eliminates the admittedly minor irritation of the six secondary wires.

I repaired the on-off switch simply by drilling out the rivets, cleaning the contacts with steel wool and then reassembling with self-tapping screws. De-oxit without dis-assembly might have worked as well, but I didn't think of that until too late. Next time.
