One thing about that phonograph. It uses a "Weathers " FM type cartridge. Not magnetic per se. A vane attached to the stylus alters the Q of a coil which is coupled to the external oscillator chassis. The demodulated output of the oscillator is what supplies an audio signal to the amplifier.
You'll drive yourself crazy if you try to test those cartridges in any device that doesn't use that oscillator!
I know as I did until the lights came on about how the thing worked!!
Rebuild the oscillator chassis,and if the styli are still good, it will work pretty well.
Enjoy!!
