Hi;
I'm trying to get my Wellsgardner monitor to work with my arcadeshop MWG PCB but I cannot get the vertical hold to "hold".
It works fine with a Vision Pro but with my recapped WG, the picture looks clear and sharp, (good cap job!) but I have to dial in the vertical hold and it will not "snap" into proper hold.
I think tha I had read a post regarding this issue but I cannot locate it again, something about a cap or the addition of a diode???
Any help will be greatly appreciated.

Problem solved!!!!
I found a rather large resistor bent and leaning onto the horoz position pins and once I ramoved the resistor from the right pin, the negative horoz. sync connection solved the problem.
Before that, no matter what combination I had used regarding the positive / negative / horoz / neg syncs, I had from totally scrambled to best - rolling vertical.
Thanks for talking me through this, (the forums that is).
EXCELLENT!
Jeff
