Hi Joe,
That must be a semi-automatic Pioneer turntable from the mid 70's. I have a Pioneer PL-115D, but it doesn't work and I haven't checked into what might be the problem, beyond knowing the drive belt is intact and fine.
Are you going to wait for more information before making a decision on whether it's worth picking up? Lee has a Pioneer about the same vintage, I believe. Are you able to test it before buying it? Although at $25, you can't ask for much. Any specifics on the condition of the stylus, or cartridge model?
Nando.
