Worked on one of those. Changer design is pretty bullet proof. I think it uses little flat rubber belts to drive various sized pulleys to change speed. Electronics package is a bit crammed, but is you basic 5 tube transformerless design.

I strongly suggest the use of an isolation transformer - especially if you're doing any live troubleshooting with test instruments.
