Power supply (PS XL 2=4=MCU): 
 
General description of PS: 
The AC motor power supply generates dual sine wave ouput to control rotation and speed of 
the AC sycnhronous motors. The signal is generated by quartz and controlled by a 
sophisticated computer based program. This allows for very smooth generation of the sine 
wave with very fine choice of speed. Each speed can be selected, finely adjusted 
independently and then stored in the memory. PS is factory preset. Connect motor cables to 
motor outputs( XL 1&2, XL 4- any ) 
Sometimes it will take a few hours for a new turntable to settle for the correct speed. When 
the PS is unplugged preset speeds will be stored.
