I realize that the boards of Stern's SPIKE 2 system are supposed to be replaced rather than repaired, but the sound/amp part of my BK:SOR's CPU board needs to be repaired and I would rather not replace the whole CPU. The game's sound is obviously compromised by a failing with that part of the board, although the rest of the game works fine. I was told by Stern that the "audio chip" on the board must be bad.
If you know of a board wizard who might take this on, I would be grateful if you would refer me to him/her. I already reached out to TheKorn per another Pinisider's suggestion and am waiting to hear back.
Thanks!

My reply from Stern said only that the boards weren't available. They didn't propose that I send the board in for repair, but now that you mention it I will contact them again and ask.
Thanks for the suggestion.
