Quoted from Friengineer:If the game is a Sys1, throw the power supply away & buy a rotten-dog. Great thread.
If System 80/A I replace the A2 power board with a new one from Gulf Pinball, I consider it a mandatory upgrade.
This is personal preference of course, but all the original A2 boards I have seen have been distressed one way or another and once you start adding up the recommended upgrades.. time and money.
Just replace it for $65 and be done with it.
