the "F" in IF
08-24-2021, 09:38 PM
whew. lots of good info. and yet. the IF transformers in the crosley AA5 i redid had tuning slugs. with fixed caps. and i'm still wondering how the design of the transformer determines the frequency at which it operates best. number of windings?, diameter of coils?, gauge of wire? as i mentioned, a transformer rated 4.5 MHz looked much the same to me as the 455 KHz ones from the AA5.
