Philco Model 41-296X with 41-285 modified chassis
#50

You have the new transformer hooked up correctly, according to your diagram.

When you first power the set up: Remove all tubes but make sure the dial lamps are in place (and have been replaced). Disconnect the speaker.

Plug it in and turn it on.

The dial lamps should light up brightly. Nothing else should happen. If any unusual sounds are noted, turn it off and unplug immediately!

Now put in all of the tubes except the 84 tube. Leave the speaker disconnected.

Plug it in and turn it on again.

The dial lamps should light up, and you should see the filaments of the tubes slowly come on. The radio should make no sounds at all.

Turn it off and unplug it.

Now, insert the 84 tube into its socket, and plug in the speaker.

Plug the radio in, and turn it on. You may or may not hear some static after about 30 seconds. Listen carefully for any odd noises.

If all is well after a few minutes, then turn it off, connect the loop antenna, turn it on again and see if you can pick up anything.

It would actually be better if you could slowly power it up using a Variac. But since I am sure you do not have one...the test as described above will have to suffice.

Final note: You did replace that 160 volt capacitor that blew out with a new 450 volt unit, correct?
