Incognito rewire problem

Thanks for your replies.The hum is in one channel only it comes and goes in the right channel.I did not think the electrical continuity was the real issue because everthing looked fine in the arm and at the base.I physically tested this also.Garth who makes the kit has replied in Vinyl Asylum to my post there.He suggests running an extra earth.So I will try various alternatives till I find one that works.

Did you not keep the internal ground wire that was connected at the stub threads. I assure that you are not the first to have this problem with the incognito. Look, I'm sorry to tell you but that kit was the "wrong" move.

I have sent the arm back to the dealer and he says he will either repair or use another kit that he has available.I had the elec. continuity checked and there was nothing coming from the blue and white wires in the left channel.This is strange as I was getting signals in both channels but incredibly bad interference also so I will wait and see.

Very bad idea to take that arm apart once yet alone a second time. I can tell you that your arm will most definitely suffer some bearing play from all the handling. You will hear distortion and sibilance in the highs. Been their- done that. I would ask for a new arm and send it to Joe at discovery cable.

I believe that installation of the Incognito kit is different for the RB 250 than other arms in the Rega series.You don't have to take it apart just remove the end stub and the base,thread wire through and fix in new base and replace stub.It should be O.K.I am dubious about the wiring itself though, as it was humming like crazy when the tonearm passed over the motor.
