Think I made a little progress today. I re-wound the coil to the specs (ohms) listed in the schematic...I did not pay attention to the # of turns...just the ohm meter. I have 2.4 ohms on the primary (1-2 lugs) and 3.5 ohms on the other (3-4 lugs). That's what the schem says.

When I jumped the connections I had squeal with the Philco tuner set about 1000. A nearby good transistor squealed about 1500 kHz and about 580-600 kHz. I then shut the radio down and soldered the connections; fired up the Philco and the squeals remained. So I think the oscillator is working...isn't it?

The speaker of the Philco has a very slight hum...that's all.

I'd appreciate suggestions what to do next. Do I start adjusting the IF coils or is there something I'm missing still?

Thanks.
Art
