[QUOTE="MusicMan_ZA, post: 525742, member: 14924"] Thanks JQ. Yes, I have, and will double-check this evening. Afterwards I tested from the shield on the RCA plug (where the amp-end of the earth wire is connected) to the tt top plate, top of platter spindle and gimbal bearing screws of the tonearm, and I got a positive reading. I also tried disconnecting the amp-end of the earth wire from the RCA plug, and connecting it to my amp's earth screw, but that made the hum 10x worse! So now it is back on the RCA plug outer shield. I also tried running a second earth wire from the top plate to the amp's earth screw, but that made no difference, so I removed it again. Am seeing some stuff about a "100Hz motor hum" - mine is just like this: :nfi: [/QUOTE]
