I have a 20 EZ that was working before I pulled it and ran through all the caps. When fired it up on my bench (using the correct 120-100 v Nintendo step down x-former) all appeared just fine. Well something when screwy after that. I mounted it in the cab but it was dead when I tried to use it. The sound board works fine..the game plays blind with sound. The fuses check good as does the AC through the diodes. I do have DC on the other side. Beyond that I can not find info as to what to test and what voltages I should get. Does anyone have any suggestions or links? Oh yes, I am getting DC at TP91 (B+). It should be around 108 according to the manual but I am at 139-140. It will not adjust down using the pot at VR601. No matter what I do it stays the same.
Thanks
