What is the "usual" source of hum between a turntable and phonp-preamp??
I just purchased a U-Turn Basic TT with an acrylic platter and cork mat with an Ortofon 2M Red cartridge. The table is plugged into a Moon Audio LP-110 phono pre-amp. Moon Audio does recommend to isolate the box away from the turntable. I have currently placed it on a 21inch formica platform stand. The hum is most audible in the lead out groove, and between tracks. The sound is very good, BUT I can still hear an undertone of hum when the volume is half way, that is between 55-60 steps on a volume control calibrated from 1-99. The pre-amp is a Conrad Johnson PV-14SE which the Moon phono box is plugged into
I aware that the hum problem can be caused by the phono cable of the turntable ( which is somewhat cheap) or the connect IC which is one of the Canare cables which cost $40.00 to $50.00. It appears well made. The U-Turn TT rep informed me that the left channel input on the table functions as a built in ground. The Moon box has a separate grounding screw which I am not using. Thank you, S.J
