hi just starting to strip a TV2 for restoration. I'm intending keeping it as original as possible (bar a paint refresh) been looking at the electrics and I think I've found the taped off battery feed, but I'm confused by a single brown wire that comes out of the junction box/rectifier and goes to a cylindrical thing (condenser capacitor ???) that's just fastened to the frame. no output from it just a single wire in.
any idea of its function and why it is there?

Thanks Steve
