Sidssp,
Thats a good point.although I suspect the impact of ac on speed control would be more audible than on pre and power amps

UPS on DC controlled tables?
Has any one tried putting in a small computer UPS to feed the DC supply on a turntable? This probably? wouldn't be so great ahead of a AC synchronous motor because the "sine" wave out of most computer UPS's is a bit squashed or triangled - but if for instance the output of your external supply is 27VDC - the purity of the sine output isn't too important ?
