The first question I would ask in the troubleshooting process is : "did it receive any stations before the restoration process started"? If so, then the problem was created during the servicing so recheck your work. If it did not play before, then given that the IF strip and audio do seem to work, your suggestion that the oscillator is at fault seems reasonable. I'm no Philco expert, but have read many times that Philco oscillator coils are susceptible to wire breaks caused by corrosion. One common test to see if an oscillator is working, is to hold a transistor radio near the troubled set and tune the tube set across the band, listening for the signal (or a multiple of the osc frequency) in the transistor set. If you don't hear anything, it's likely a non-functioning oscillator?
