I'm working on an RCA 45ey2 and found a link to the breakdown of the RP-190 turntable used. http://oldtech.net/TT.html Had a question about the 1 Megohm resistor noted in the last page parts list. It appears to be visible connected to the pins of the muting switch. My unit does not have this resistor. What is it for and should I add it?

It's a load resistor that was used on the attachment turntables. It limits low frequency response. It's not necessary on units with built in amplifiers with small speakers. The attachment models like the 45J-2 didn't have much mechanical isolation. The resistor prevented low frequency acoustical feedback when used with larger amplifiers and speaker systems.
