<DIV><FONT face=Arial size=2>If I had to guess at your problem, I would guess
that you were overdriving the hardware, voltage or current wise. If you
drive the pots or circuits with too high a voltage or current, they may appear
to work for a while, but eventually they'll burn-through and fail. Just a
guess, but it would explain your symptoms.</FONT></DIV></BODY></HTML>
