I would like to add a second record player to the 46-1213 console to provide 33 1/3 RPM capability. I was thinking of the AT-LP60 which has an AT dual magnet cartridge, with a switchable preamp providing about 36 DB gain.
The current changer cartridge output feeds into the transformer, out of the transformer through an R/C network of 220K resistor and a .001 MF condenser parallel with a 4.7 meg resistor to ground into the grid of the 7AF7 phono amplifier/phase inverter.
Question: What do I need to do?
