My pride and joy in the world of pinball is an autographed Evel Knievel home version. We have had a lot of fun playing this game. A few years ago it failed to power up. And there it sat. Until recently I got ambitious and while knowing nothing about electronics I was able to repair the power supply, put it back together and BINGO...it lives. I would however like to replace the series 1 power supply which I have learned is notorious for failure and ruining the mostek 3850 ic. My question is, would it be possible to use a modern switching supply like the one pictured below. I feel like I could build a simple circuit to step down the 24vdc to the required 18 and 22vdc. It already has the correct 5 and 12vdc I need to run the game. Any help would be appreciated.
