Thanks for posting the schematic.
Its a AA6 set with RF stage with slug tuning on the IFs. Did not see a mention of the IF frequency but normally these are 455 KHz.
1) Fully close the gang tuning cap with full volume.
2) Inject IF signal at pin 7 of 12BE6 with enough strength to hear a tone.
3) Adjust slugs on T2 and T1 in that order for loudest tone. Reduce signal level on generator as needed to still hear the tone.
4) Next the RF front end. Check position of dial pointer across dial for full range. Go to 1500 on dial. Set generator to 1500 KHz and place the RF cable near the antenna to receive the signal.
5) Adjust oscillator trimmer C6 on ganged tuning cap for max tone.
6) Adjust adjust antenna trimmer C2 on ganged tuning cap for max tone.
7) For RF stage, adjust C4 trimmer on ganged tuning for max tone.
7a) Move dial to 600 KHz, adjust L2 slug of RF amp for max signal.
