I just picked up a SF that has been home used since 1989. It's only issue is that there's no sound. So far I've tried a new speaker and made sure the settings are correct, but still not even a hum. So before I start getting into test points on the board, I have a question about the connector on it. In the pictures you can see that the block is too big for the connection on the board, but it looks like it's original. The positive thing is that the 2 wire colors in the block match what is on the schematics for those pins. Is this the same on everyone elses machines? Any other thoughts of what I can check? I've turned up the volume on both pots, but that didn't do anything. LED flashes on the board are normal.

Thanks,
Steve
