I am restoring and selling a DE Playboy 35th and have it working and in beautiful shape except the sound. While replacing the main 68B09 chip on the sound board, I noticed another chip that was never installed correctly (pin bent and touching pin next to it above the hole). While replacing that chip I screwed up the board and burned up a trace or two. So two questions:
1. Who can I get (if possible) to repair the board? If not possible then...
2. Where can I buy a DE 520-5002-01 sound board? I have checked all the usual suspects in addition to eBay and that board just doesn't seem to be available anywhere. It seems really scarce. Any ideas?

Thank you. As a follow-up, do you know if the newer DE 520-5050-01 is compatible with the older 520-5002-01 ?

Nevermind, I found the answer to that:

Sound Board Generations.
There are several generations of sound boards used in DataEast/Sega games. As the games got more advanced, the sound storage requirements grew accordingly. These sound boards are NOT upward or downward compatible.
