So at first I thought the audio itself was running at like 4x speed, but I believe it's actually queuing the audio too fast; Kenobi's "May the force be with you" isn't higher or faster, but the music behind it sounds like it took some uppers. My current theories are:
1. An issue with the clock
2. Somebody replaced a RAM chip with a faster speed chip?
3. An issue with the audio processor

Any ideas would be helpful. Has anyone seen this before? Thanks.

Thanks for the quick response Chris. Here's a video:

Thanks.

Ok,
1. Apparently it was working and on the floor at some point before my time, but no documentation of issue.
2. I can't get into a sound test, even though the manual says it's there, it jumps from Burn in Test straight to Speaker Test. The audio is looping fast in the background in every menu except when I run a Burn in Test; things got real low and crunchy.
3.The only playfield issue I can see is that the bar motor is stuck down, but I unplugged it and all it's corresponding switches and that didn't effect anything,
4. I reseated all socketed chips and noticed that PIN 19 of the CN21 ribbon cable on the CPU BOARD was bent out from contact with the connector. When I tried to straighten it, it immediately broke off. Also PIN 20 was missing. CN21 connects to CN1 on the AUDIO BOARD. Pin 19 is marked as 'E' on the schematics and pin 20 (which was gone) was marked as 'N.C.'. I'm assuming that's normally closed, and is E emitter?
5. I figured I'd try a reboot and now it plays the 1st 15 seconds of audio, cuts out for 30 seconds, and then audio comes back in.

Sounds good. Thanks for your input on this Chris. Both my flippers are out, and I won't be back here to address it until Tuesday, so I'll try to post some gameplay then. Thanks again.
