My pleasure. Just to clarify, the bridge rectifier to replace is DB1 on the power supply board. Here's what you need, quote...
Replacement Bridges and Diodes.
All the stock bridges installed in DataEast/Sega games are 35 amps 200 volts with lug (not wire) terminals. The original part number will be something like "MB3502" or "MB352" (signifying 35 amps at 200 volts). A replacement bridge can be any voltage or amp value at that rating, or higher. Since the cost is usually no different, buy 35 amps 400 volt replacement bridges with lug terminals. These are available from Competivitive Products Corp (800-562-7283). Radio Shack even sells 35 amp bridges at 50 volts (which isn't enough voltage). But if you look at the bridge inside the Radio Shack package, often then are labeled 3502 or 352 (35 amps 200 volts), and not 50 volts. Always buy only the labeled bridges from Radio Shack. Sometimes these "35 amp" bridges are labeled 1001W (10 amp 100 volts!). Obviously put that one back and grab another!
