Capehart-Farnsworth P-45 Record Changer
 

Does anyone happen to have a Rider's schematic for the Capehart-Farnsworth P-45 record changer? Or the P-2 that preceded it at least?

I don't want to move on to my TV project till I finish with the CK93 radio/P-45 phonograph combo. I'm trying to find out if I'm missing parts on the changer. I suspect something is gone or not working properly because the platter spins continuously and there doesn't seem to be a way for the idler to disengage, including when the record runs out. There is a button on the platter that seems like it'd be responsible for detecting a record being present, but it doesn't appear to actually do anything that would effect the idler.
