I recently purchased a Galaga power switcher as sold on the arcade shop website. The machine previously didn't power up, and now does, but I'm getting a "RAM 4H" error on the video board message. I've gone ahead and ordered replacement RAM, but have been told by Steven at Arcade Shop that it's possible the power supply isn't putting out enough power and to verify that it's putting out +5.2. While I can see on his website (http://www.arcadeshop.com/galaga/galaga.htm) where to test this on the logic board, I'm not sure how to adjust the amount to equal 5.2?
Also, can anyone tell me what the white circular knob near the LED on the power switcher does?
Thanks for your help!
