Ah- I see! The guy who fixed it all for me was an electronic engineer- this included rebuilding cylinders, wiring, lubricating and tightening turntable and all rubber- pretty much everything has been restored- the cutter head was restored by gib at west tech, and the roller by terry's rubber rollers (both in the US). had a lot of help by the people at lathe trolls. Its an EV dynamic mic- we're currently playing around with different kinds- recently tried an omni directional mic, and it made no difference to the recording!
