I just got a 1242 from e-bay, It came in better shape than some others I bought there but of course it has a few problems. The counterweight thumbscrew is missing, does anyone know the metric size of this screw, maybe I can find a generic at the hardware store for now so I can lock in the counterweight and test it. It's a belt drive changer, it's not in the library. Does anyone have the Manuel and Service Manuel to upload to the library?? The deck looks like a 521 with no strobe light, but it's a changer with the single - multiple head shell. Any ideas on another model I could download the Manuel's from for servicing would be appreciated!! Glenn.
