so what was the problem?
we beat on the boards with chop sticks, resoldered both boards, put a heat gun on it, dang thing still had problems, trouble was getting the sound level to drop long enough to trouble shoot it, so we put on some ear goggles and hammered it on 11 for five minuets, and like magic, it cut out, long enough to pin point the trouble,
it was this guy>
(notice the cheese ball feedback resistors sitting there waiting to break, only bad part of the build)
