Philco 40-180 no tuneing
#12

I was working with Forest on this. Here is the strange twist. If We take the wire off of #1 of the oscillator coil and connect it to #4 we can receive the AM stations between 540-1130 but not beyond that. The coil ohms out as per the schematic. Not running into this before is it possible that the coil inductance is bad even though the resistance is ok? The push button switches work fine it all seems to be centered in the oscillator coil. Does anyone know what the inductance reading of that coil should be?
