Hi there.
Working on a WG6100 from an old Tempest. This monitor had several problems but all have been resolved except for one: the focus pot on the HV has no effect. The game will come up well focused but after a few minutes the focus goes south and everything is a blur. After a while it will return to a reasonable state, but it may revert to unfocused later. Very strange.
* Brightness control works fine.
* Cap kit done
* Run in a working Space Duel
* Swapped deflection boards and no change.
I have access to a couple other wg6100's so I can swap major parts as needed.
The flyback was replaced within the last couple of months and the works appears solid.
The focus pin inside the neckboard connector appears intact.
