I'm about to modify my totally stock Rega P2 with the OL structural mod. and DIY Cardas (I think) tonearm cable, RCA's & cartridge clips.
Wondering about the correct grounding method - I've seen a few different variations. Also, is my thinking right on the Cardas cable? Any better suggestions?
There is a ground wire attached to a brass clip insdie the armtube just in front of the c/w stub. Uncrew the plastic stub and you will see it (if you install the OL c/w youŽll see it sooner or later).
Rega solder this to the blue cartridge wire (left channel minus) which is not a great idea. You can use this wire to solder to an external ground wire or just run a completely new ground wire up to this clip and solder it on and reinstall the clip, it just snaps into the threads.
I personally don't think the Rega HOTROD method of running the ground wire up to the headshell and attaching it there is a good idea. It is much more effort and has no technical advantage.
But the base of the arm, the threaded brass part, is grounded tot he arm tube through the bearings. There is some resistance of course due to the small contact area of the bearings but a ground it is.
That sounds like the way to go.
