Hi Ritchie,
Have you checked to see that your oscillator is running? In this set it is part of the mixer (1A7) circuit. You can do this easily if you have another working AM radio. Tune your Philco to 1000 KHz, then tune your other radio to 1000 KHz+ 465 KHz = 1465 KHz and place it near your Philco. Then move the dial up and down a little on the second radio. If the oscillator circuit in your Philco is working, you will hear some squealing (that changes as you adjust the dial) coming from your second radio.
If you hear nothing, then it is a good indication that the oscillator is not working on the Philco which might explain the lack of sound.
Good luck,
Jon
