In the title of this thread, it is revealed that the turntable in question is specifically a Goldmund Studietto, not a JVC or anything else. Steve Dobbins would know what to do and what not to do with the bearing. Same applies to the servo mechanism. Dobbins is a recognized expert on the Technics SP turntables and has marketed his own revision of the SP10 Mk3, as a separate product under his own brand, "Kodo the Beat". If Steve would work on a Studietto, it could not be in better hands.
Goldmund Studietto repairs
Bought mine in 1986. Not used in years as tracking arm stopped working. Now want to repair. Need a specialty repair/refurb shop. Thanks for suggestions. I'm in Vancouver, BC but won't hesitate to ship. Cheers to record lovers. ( I have a Spectral Cartridge. Will it need refurb?)
