Quoted from dbpbandit:I found this at Great Plains, is this the correct one?
Part Number LM317AHVT
Yes, that's the right regulator.
Quoted from dbpbandit:Once I get this sorted out then I can start looking at the sound board. I see they sell a cap kit and new connectors for these, should I go a head and order the parts?
The capacitor kit is cheap so grab it. Have a close look at the 34 pin header connector at the top of the MPU board and the sound board. If either looks tarnished/corroded then I would buy the interface cable too, and get some 0.1" pin headers to replace the tarnished ones.
At some point you may consider getting a bunch of 0.1" and 0.156" pin headers and terminals (and housings if needed) in case you have to start repinning other connectors.
If you don't have any, grab a bag of twenty 1N4007 diodes, 3pcs TIP102 transistors, various spare fuses for your game, 2pcs 2N5064 SCRs, 2pcs MCR106-6 SCRs. The Transistors and SCRs drive the solenoids and lamps and might come in handy one day.
