I have restored three 48-482 radios. I made only very minor adjustments to the coils to tweak the dial calibration. Never had a problem. I used a
wooden stick with a ferrite taped on one end and a copper wire taped on the other to determine the direction to tweak. If the ferrite causes the tuning to be closer to correct then the coil needs to be closed up a bit. If the copper causes the tuning to be closer then spread the coil. The adjustment is very sensitive.

Kind regards,
Terry
