That Electrola is an excellent find. As others have mentioned, it is quite rare (especially the changer, which probably had a very intricate and complicated mechanism [for the time]), so I'd say go ahead and try to get it working, even if it means using the original RCA amplifier and a '50s changer (Garrard or some other high-end brand, but good grief not a '70s BSR) for now. (I had a Zenith integrated stereo system years ago with a BSR changer, and had not one bit of trouble with it, but mine may have been a rare exception to the rule.)
The Electrola's cabinet looks good too, and made of real wood, no doubt--not the pressboard of which today's media stands, etc. are made.
That RCA amplifier looks like it may have been originally intended for use with a small sound-reinforcement system. For many years we had an Allied-Radio Shack (IIRC) amplifier, vintage 1950s or so, at the heart of the sound system in our church. That amplifier wasn't too terribly powerful, but it did the job until it was replaced some years later by a larger amplifier which I was in charge of setting up and taking down before and after Sunday services. Can't recall the brand, though.
