Seeburg Home Stereos
I posted this link in another thread, but here it is again.
The AP-1 in my wall was actually intended to be a free-standing unit, but I didn't have anywhere to put it. Besides, the cabinet was pretty badly scratched.
I just happened to have a place on my bedroom wall that backed up with a hall closet that turned out to be about an inch wider than the machine. A few hours with a Sawzall and some spare lumber later, and it was in.
The motor is synchronized to the power line, so you don't have a speed control. That was only used in machines that needed to be able to play two different speeds.
Because it holds 50 albums which each have 2 sides, you can select any album side by dialing in a two-digit number.
The machines were made between 1967 and sometime in the early '70s. They were very expensive, and are fairly uncommon.
Seeburg made several modifications to the mechanism to improve record handling and sound quality, and these machines have fairly impressive specifications. Underneath it all, there's the same basic mechanism that was used in Seeburg's coin-operated machines from 1949-1984.
