The G07 in my Galaxian cocktail is a little strange...
I was adjusting the B+ on the G07 in my Galaxian cocktail over the weekend when I noticed the adjustment point was in an odd place. Rather than being flat on the chassis, the pot was at the back of the board like the other adjustment controls. Even though it was in a different place, it was still properly marked on the PCB. Instead the V. Hold adjustment is around the area the B+ adjustment usually is, again, marked on the board. Additionally the chassis doesn't seem to have a V-Lin adjustment or a Horizontal Centering jumper. Also the flyback only has a Focus control, no screen. I've been told the pot on the neckboard is the Screen control, that it was relocated on some monitors. All I have on the back of the chassis are the Vertical Centering jumper, V. Height and H. Frequency adjustments.
There's also some kind of daughterboard on the chassis?
So my question is, has anyone seen this before (probably) and where's my V-Lin adjustment if I have one? Is this something fairly common? Also is my Screen control on the neckboard? The adjustment there seems to have the same effect that Screen would. Am I going to have any problems if I go to recap this chassis?
Thanks!
