re: I'm lost in a sea of High Voltage!


The high voltage may be fine, and the display still unacceptably dim.
Check the screen grid voltages for a start, although where you're going to
find a listing of the "nominal" voltages is beyond me.  Considering the
use that these arcade games get, though, it's entirely possible that the
CRT - specifically, the cathode in the electron gun - has gone to the
Big Photon Factory in the Sky, and a tube replacement would be your only
hope.  Good luck!
