Unless you have an early production model, there should be three trimmers mounted on the side of the tuning condenser.

Alignment is simple, but you should do this carefully:

Tune your signal generator to 1400 kc.

Tune the Philco to 140 on the dial. Turn the volume control wide open and use the weakest possible generator signal so that it is audible without being too loud.

Adjust the trimmer closest to the back first, then the one in the middle, then the one in front. Adjust each for maximum output.

You may not hear the signal when the Philco dial is at 140, so tune in the signal and carefully adjust the trimmers so the 1400 kc signal "moves" to 140 on the dial. This is done by readjusting the tuning condenser as you adjust the trimmers.
