I wanted to see if anyone out there had information on the Well Gardner k4500 besides schematics. I recently bought a Galaxian cabinet that has one of these in it, and I could use some help on adjusting settings. This particular chassis seems to have a lot of knobs to mess with. I got the convergence looking better this weekend and had to tweak no less than 16 pots on the neck board along with the 2 purity rings.
If I were to start somewhere, I would be interested if anyone knows about the various adjustments on the chassis itself. The chassis has a small auxiliary board that has a switch and 9 pots. So far, only one pot seems to do anything for me (the vert hold, I think). There is also a standalone pot above the flyback that seems to have no effect. If anyone is interested, there is a picture here: http://www.therealbobroberts.net/k4500.html (thanks, ieure for the link). I would be really grateful if someone could help shed some light on these control for me!
Thanks!
