Up for sale here is this movement mechanism from a Pioneer PL-55DX turntable. This may need lubrication and adjustment, but should work fine after that. This should work for the PL-55, PL-55D, and PL-55X turntables as well, and may work for more, but I do not know for sure. Please see my pictures for details.
US shipping and handling is $10, and international is $28. If you have any questions, please ask.
I have lots more Pioneer PL-55DX parts listed--feel free to take a look! If it's not listed, I don't have it.
