Open boot, down deep in the back left hand corner. There a little black box with 3 thin wires and 1 thick (1cm dia) wire coming out of it. The box is just to the left of 2 round cylindrical components. What is this black box? TIA.
Thanks. It seems to interfere with radio reception as when I touch it the reception becomes much better (perhaps a grounding issue?). Anyway I have some ferrite cores on order so maybe that'll sort it.
