Make sure the 4 pins from the cartridge are seated properly to the cable's coming from the tonearm; make sure the insulation is on all four of the cables that clamp to the pins. I had a hum a while ago as there was one insulation missing. Dealer replaced insulation (a different dealer from which I purchased) and hum gone. (VPI TNT and had hum turning on motor and moving tomearm across record by hand).
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.
