Hi Andre
I just looked up your 42-321. Your set does not have a low frequency padder adjustment. This was included in better radios, including most older Philcos. Designed to be adjusted at the low end of the AM band, typically 600 kc, its purpose was to make the local oscillator track accurately with the set's IF (intermediate frequency).
Since the 42-321 does not have the low frequency padder, you are going to have to live with a set that is somewhat misaligned on the low end.
The bean counters, I am sure, deemed such an adjustment unnecessary on cheaper radios after a time. Hey, as long as it's close, who cares, right?
Finally, if you want the best alignment possible, you are going to have to invest in a signal generator and have some means of measuring the output, whether it be an output meter or oscilloscope. Then follow the factory alignment instructions to the letter. This is the only way you can accurately align your set.
The ear method is OK in a pinch, but is not the correct way to do things.
