I have a Space Invaders Deluxe cab that has no audio. I checked power coming out of the transformer, all good. When I check voltage across the capacitor shown on elektonforge's website I am only getting 3V and it should read 18V. I replaced the Cap and the IN4004 diode and still no change. Any Suggestions?
 
There's four A14 diodes that make a bridge to turn the AC volts from the transformer into DC volts....I'd check those.....and the 3 amp fuse that's in line after the transformer voltage. This voltage also goes up to the attraction panel lights. A shorted light socket could take out the fuse. If your attraction panel lights are working....you've got a connector issue.
