Anyone Know How to Fix Radios?

If the coupling on an IF or RF transformer is too tight, you can get double humps, similar to 60KHz apart, like what you described. Looks like the IFs are tuned by variable trimmer caps, but if they were adjustable slugs I'd say that they were set too close together. I see a :gimmick" on the RF coil in the schematic diagram, if that is too much capacitence (too tightly wound) it might produce the double humps.

Double humps have their uses, one can produce say a pair of humps with a separation of say 5KHz, which can make for higher fidelity (higher audio frequencies) from radio stations. But be careful that the carrier isn't attenuated too much, or distortion will result,
