I have restored Philco Model 96 Lowboy, and understand there was a similar Model 296 that included a phono turntable. I recall seeing a schematic for the 296 with a connection for the phonograph. I've been thinking of modifying the model 96 to use with a Garrard RC 121/4D turntable. I realize I'd need a preamp if I use a newer cartridge. Would anyone have suggestions for the modification?

I should add that I have an AM transmitter and have played 78RPM records as well as CDs through the transmitter and Model 96. I think however that it would be preferable, were it possible, to simplify the setup. In fact, it would be great to play CDs direct to the Philco as well, if feasible.

 I don't think that you would need a preamp at all, the pickup on the model 296 was magnetic so it would have have had a lower output then even a newer ceramic cartridge anyhow. There is an advantage to using the AM transmitter though, you end up using the RF amps in the model 96 as preamps ahead of the audio amplifier stages rather then bypassing those and the detector.
