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.

Hi Rich,
The contacts should not arc - this usually means the Detent Switch is not set up correctly. The Detent Switch sets the time that the connection is made through the wiper - it should only close when the contact is already made - and thus should not spark at the point of contact.
Check it out!

Rich, I had this same issue (popping in the audio stream while scanning) on a tormat machine once. Ron suggested a faulty cap on the scan control assembly in the TSR. I checked and a leg had detached from the poor solder joint. I resoldered and the problem disappeared. Not sure if this is your issue but worth a look.
Regards, Rick
