So, first post. I picked up an asteroids cabinet free off craigslist almost 10 years ago that according to the giver had "recently stopped working" and have finally gotten around to trying to see if I can't get it working.
Spot-killer is on but otherwise it seems to play fine. I've gone over some of the obvious stuff, refluxing and recapping the deflection board and HV supply didn't fix it. I have a set of chasis transistors and a few diode bridges on the way. (The transistors aren't shorted, but they were cheap enough.) The only odd bit is that R100 is *toasty* and R101 is cool.
I think the X/Y/Z voltages from the game board are far too low but... the game board is.... just weird in a distinctly hand made way. What am I looking at here?
