It could be any number of things, I'd get it to a tech who can get his hands on it and see what's really going on. terryc Senior Member Username: terryc Post Number: 1569 Registered: 11-2004 Posted on Saturday, May 14, 2011 - 6:06 am:    edwin...I am the part time tech!!!!

A simple continuity test w/ your meter should tell you if they fried.... From my experience they're usually the culprit. terryc Senior Member Username: terryc Post Number: 1570 Registered: 11-2004 Posted on Sunday, May 15, 2011 - 5:27 am:    pace..will do..pulling the amp section today whilst I have some time
