Cave Dweller, no clean repeat

Last summer I built a Cave Dweller and let a friend who plays in a one man band borrow it for a while. During one of his shows some water or beer was spilled in his gear. The Cave Dweller stopped working.

The problem is when the dwell is at zero and the echo is at max it there is no clean repeat like there should be. The filtered repeats are being sent back to the input and oscillating when dwell is turned up. I checked the voltages on the PT2399, nothing looked out of the ordinary.

1. 4.93 V
2. 2.46 V
3. 0 V
4. 0 V
5. 2.81 V
6. 2.46 V
7. 0.71 V
8. 0.73 V
9-16. 2.46 V

The voltage regulator looks fine too...
1. 4.95 V
2. 0 V
3. 9.33 V

I'll play around with my audio probe some more tomorrow, so far I have audio coming into the PT2399 on pin 9 and coming out on 12,14, and 15.
