I recently got a 46-1203 at an antique store, and the radio portion functions. However, the tone arm was missing the cartridge upon further inspection of the radio. I understand the d-10a player had a magnetic cartridge and the d-10 had a crystal cartridge, but my radio chassis doesn't appear to have any kind of magnetic pre-amplifier. Also, the ends of the wires left behind had the pin connectors I've seen used on crystal cartridges, instead of solder tabs. There is also a notch at the end of the tone arm as if an adjustment screw stuck out there. Is there any difference in the radio chassis used with each model of phonograph, and would it be possible to insert a crystal cartridge?
