JC;
The original 79rpm changer came with the unit. I removed it and placed it in a storage box and it will be returned to the owners when the radio-phonograph is returned to them. They had no desire to keep the old changer and wanted a modern changer that would play all speeds and sizes of records. The BSR provides that capability for them. The BSR-310 I chose came with a Shure magnetic stereo cartridge, so they will be able to play stereo records without worrying about damaging the records.
I have been working on the changer installation today. I have mounted the Bozak preamp to the rear of the old changer base and made a Y-audio cable to bring the left and right channel outputs together for a monophonic signal. I have been re-organizing the associated cables and securing them so that they do not interfere with moving parts such as the door moving hinges and the rotatable AM Loop antenna. I made a trip back to a hardware store today to get parts for adding an AC outlet to the right of the radio chassis which will fasten to the wooden horizontal rib that supports the rear of the radio chassis. The preamp and the changer will plug into the receptacle so that for service the changer can be removed separately without having to remove the radio chassis. The Phonograph function AC cord will connect to the receptacle and when the radio is switched to Phonograph operation it will turn on the AC to the changer motor circuit and the solid state preamp at the same time.
I will take some pictures when done.
