Hi Dan,
Oopsie, my bad. Was looking at 38-12, clicked on the wrong one, But I think that the issue is the same. IF frequency on this set is 470KHz Check Cap # 10, a 3500 pF (0.0035 uF) mica cap and Cap#14, a 250 pF (0.00025 uF) cap. My theory is that if either of these caps are bad, you will have to overcompensate to get the beat frequency to be 470 KHz and therefore can't get the dial to "track". I may be wrong, but this is my guess. The IF is a fixed frequency. If you can peak the IF to 470 KHz, then the IF transformers are good.
