Chuck, you may already have this but if not, maybe you can poke around there.

Hi Chuck,
I'm not sure if you still need this info but if you do here it is LOL

The problem could be on the top board or in the pre-amp, cabling etc. First , I would swap out the Larger P031AH chip for String 5&7. The (smaller) EPROM chips don't seem to go often. Sometimes just taking the chip out and putting it back in the socket a few times will repair the fault.

I'm surprised that some of the info I put on /sites.google.com/ is still there. They closed that down about not long after I got the info up there and sorted out
