Identifying value of potentiometer

Post by freya » Tue Feb 03, 2015 1:11 pm

Any ideas on the value of this switched pot from its number, its from another scope but from about 1940`s
The track is cracked through.
I had though about measuring up to the break, then from the other end up to the break and adding the values but the track measures very odd some distance away from the break.

number on it is ZNS-MTSAR-50286

Is there a pot with the same number used elsewhere in the scope?

Hi Rich, no its the brilliance control with quite a high voltage on it. Not seen such a thick track on a control.

I may have a switched 500k pot off an old scope if any good to you.

Andy.

Thanks for the offer Andy, I have a few tins to look through and I am hopeful there will be one amongst those.
