Marantz Speed Control Module
Turntable Model: TT-2000
Part # 631726
Complete with the mounting screws
Both the Coarse speed select and Fine Speed adjustment controls are supplied - WITH KNOBS
Set currently for 50Hz operation, 45rpm and 33rpm
Removed from the turntable, fully tested prior to removal - speed is fine and reasonably stable. It should be realised that this model control board is NOT quartz crystal locked, so some small drifting of the speed is inherent in the design.
Power is brought onto the board directly from the AC power transformer (9.5-0-9.5) near the 2x blue electro's - this AC power transformer is advertised separately
I do not have the circuit diagram but have left very short lengths of the colour coded wire on the wire wrap terminals to make installation very simple - just follow the colour codes.
