I finally got the machine put back together and I have a problem with speech and sound. All of the sounds are present except for the background sound, which comes and goes during gameplay, but works fine in test mode. The speech was working fine, but now nothing during gameplay. The speech does work in attract mode and will only do tilt, tilt in test mode. When it is suppose to speak in test mode, all you hear is the lower playfield (windy) sound. I have reseated and cleaned the chips with no change. Anybody have any suggestions?
 
Make sure you've got good +5VDC power to the board...
...but it kinda sounds like a bad RIOT (6532) to me.

(Although the other ICs in the input lines, U16 & U16, could concievable be the problem too)
 
I repinned the sound board connector and associated connector on the driver board. I now have all of the speech during gameplay. The background/LPF tunnel sound works sometimes for a couple of games, and sometimes it quits mid game. These 2 sounds are the only ones I'm having trouble with at this time. The 6532 on the sound board does seem a bit hot to me, not burning to the touch, but still too warm( I think). Is this normal, or could this be possibly causing it?
 
As of now, the speech and sound are all working. Of all things the dip switches were a little flaky and causing them to cut in and out.
