Tonearm wiring problem

I need some help with my tonearm internal wiring.
I think something has disconnected at the DIN connection end.
Does anyone know a good dealer or individual who can look at this. I live in Richmond Surrey. Cheers.

Dave, did you ever find someone? I have a similar issue with a Jelco tonearm.

Thanks.

No I didn’t have to, it was the fault of the phono cable.
Sorry.

Ah, ok thanks.
