If you have a Nottingham with the Rega tonearm, you can send the tonearm to Britaudio (www.britaudio.com). I sent them my tonearm and had Mr. Wharton install the Incognito wiring harness. I now have better wiring and a proper ground. I sent out the tonearm by UPS on a Monday (from Ohio) and had it back by the weekend.
