VIPfx T-Wrex II question (Fixed)

[strat68]

I just realized that I had forgotten to pay attention to capacitor voltage and was running it at 18 volts.  What are the symptoms of doing this?  I'm getting occasional sound out of the distortion side that sounds great.  The thing seemed to worked before boxing it and now works sometimes after taking it back out of the box.

Alternatively I also think my real problem is some type of connection issue on the board itself.  I can always trace a good signal to lug 3 of the volume pot.  Only some of the time does it the signal come out of lug 2 and make all the way to the output connection.  The pot is OK as I switched it out and checked the new one before attaching it.    The signal at R23 is also fine (as expected).  I've re-flowed solder on the parts from IC3 to the volume pot.

Here's the schematic:  http://home.comcast.net/~gprause/BuildDocs/T-Wrex_II_V3.2_Build_Doc.pdf

Any info is greatly appreciated.  This things sounds awesome when I can get sound out of it.
