Rega’s ground wire is routed through the tonearm which is why we see so many threads about Rega and hum. It’s poor design. The table tries to ground to itself. Doh! Let me guess, your hum also gets louder as the tonearm gets closer to the motor/spindle? Does the hum change if you touch the tonearm?
turntable hum
Hi I have a Rega P5 table ,with new Exact Cart, got it used , it has a hum and gets louder as the volume goes up.It doest have a ground wire, I thought might be my prima luna integrated amp or my pro-ject tube box DS, so i hooked up to another receiver (outlaw 2160 ) and still has the hum, is this normal ,i don't think so ! Any ideas as to what would cause this and how to get rid of this HUM , Thanks Lloyd
