The BSR 310 changer came with a Shure M75CS cartridge which is designed to track at 3-5 grams and provide an output of about 9.3mV and a load resistance of 47K ohms. I do not know if this will be sufficient for the Philco 46-1226 audio amplifier circuitry. There is a 150K ohm load resistance attached to the phonograph input jack on this radio, so for now the only thing I can do is to try it and see what happens. I have a suspicion that it will need a preamp.
