Try floating the gound on the TT motor if your power is 120VAC. If it is 220, keep the ground. Check your interconnect cables, sometimes the fit is bad, or there is grunge on the inside of the RCA. Also, isolate it into one channel if possible. If both channels, it is likely a ground loop. Everything should be gounded at the same location/wall outlet if you are on 120VAC. Have only 1 component gounded, the rest floated, for 120VAC. Cartridge wire as mentioned above is a common problem. I have the same table and it is quiet as a gravestone. Barring a motor problem, it should be very quiet. I don't use a separate ground wire to the preamp. My preamp is gounded though. Be sure to tighten the motor pulley as mine was loose and the speed was off. Jallen
Help VPI turntable hummmmmmm
I have just installed a new Naim system with a VPI Scoutmaster and the TT hum is not quite deafening..............but getting there. Can someone please help!! Do I need to earth the TT to the phono stage? If I do I have tried this but no success. What am I doing wrong. There is also an audible 'thump' when switching the TT motor on or off.
