Rega P10 - I have a hum

The solution is not exactly correct, don't drill a hole to the DIN connector and don't isolate ground connection.

- Just unsolder black wire and the ground pin from the left negative pin and blue wire.
- Solder the black wire to the ground pin. The ground pin on DIN connector is the one in between channels, between green and blue. It needs to be connected to the arm body, that's why there is a metal plate soldered to it. Normally it aligns with the screw hole seen in the picture above and screw ensures electrical connection between ground pin and tonearm body.

You can do what you want, I did as described in the link and it works perfectly.

If the turntable is under warranty, the best is to go to the store.

You’re right—the OP is free to make his own decisions. We’re all just trying to be helpful.

Yes..this correct way.
to break the ground loop, you need an extra wire for grounding. Rega tonearms have no seperate ground wire. I hope this solves the problem and the error isn't somewhere else.
With some phono amps the tonearm tube acts like an antenna.
Exsample no wire.

Another thing to check is whether the tonearm body is connected to the turntable ground. If both the turntable (or bearing) and the tonearm are grounded separately via separate grounding wires and also connected to each other through the turntable chassis, this could create a ground loop and cause hum. In such a case, one of the ground wires should be disconnected.

Tutorial how ground rega arms without modification, last tip of video maybe it helps no gurantee.

I seperated my P10 black tonearm wire out from the blue one (sounds better with my DIY ANK L5 phono stage). Even without the connection between tonearm ground wire and the SUT chassis/ phono stage grounds. There is no hum.
