[Jukebox-list] AY Contact Block sparking

Good evening

Attached is a video link demonstrating the arching issue of the outside pin on the contact block. This arcing is causing a pop in the speakers when scanning from right to left. I think I recall Ron Rich stating these can be retipped...maybe? If so, with what? Replace the pin in the contact block or replace the entire contact block. Anyone have any experience in this? Other that the annoying clicking sound..the box is fully functional, amp, selection receiver, and pulse amp have been recently serviced. Machine is on freeplay.

I'm leaning towards this pin..becasue if I gently pull down on it.while scanning..popping stops.
