Hi Phil,
Sounds to me like your oscillator is not working. This generally happens when you get the same station across the dial. To see if it is working take another radio, a transistor one just because it's easy to handle and set your Philco on 1000khz. Tune your other radio to 1460. That's 1000khz + your I.F. frequency of 460khz. You should hear a squealing in your radio. If not then your oscillator is not operating. Change the tube and for sure check the osc. coil which is Part # 8? Seem Philco's have a problem where the wire ties into the coil lug. Check continuity and look for some green corrision at the terminal. It also would not hurt to clean the band switch. I'm sure some of the guy's can help you more but it's a start.
