For anyone remotely interested.. Here's a vid of the fisher studio standard fvh-p915kv in action after a service. Had to short out the faulty dew sensor temporarily and makeshift a new idler, but she's going. Loading motor seems to be a bit noisy since the service, gone the same way as the fvh-p905. Wondering if part of the mechanism doesn't like the lithium grease....
