I restored a 53-1750 radio phonograph - all new caps, resistors and replaced any bad tubes. The radio picks up the AM stations but only fairly weak. The phonograph works great. I don't seem to be able to align it with my signal generator. I tried hooking in the signal generator directly into the radio as per the schematic instructions and I've tried to put the output wire near the radio's antenna and I get no signal coming through the radio when the generator is set to 455 KHz.
I know the signal generator works and it's signal output is very precise, because if I set it for any regular AM channel - I can hear the signal no problem - i.e. if I set for 750 KHz AM - it comes in loud and clear with the radio set to 750 am. So my question is - can't I just set the signal generator to any regular am station (rather than 455 KHz) and turn the little scews in the low frequency "coils" so that the regular am stations will come in as strong as possible??
