I think that it's time to break out the volt ohm meter and start taking some measurements, starting with the power transformer windings, first resistance readings, then AC voltage readings. After it's cleared then you can check the DC voltages on the tubes, and the resistance of the IF cans, and the coils. If all of these check out I would not waste any more time trying to troubleshoot the set, replace all of the paper and electrolytic capacitors, and any out of spec resistors, the chances are that the set was retired because it no longer worked. One common fault this era of Philcos seems to have is a failed output transformer, that may not be why the set does not play, if half the primary is still good it should produce some audio if you touch the grids of the power output tubes.
