The trick for best performance after careful servicing, is to bolt the deck to a solid mass to sink away any vibration, Layered plywood plinths are popular, no hollow boxes or decks bouncing around on springs!. The revival of interest in These Garrards and the equally good
Lencos , is mainly down to the superior speed stability when handling transients, belt drives tend to slow down microscopicaly but audibly. If you are handy with woodwork you could build up a nice deck and show a healthy profit on the spares.
