Hey everyone. I got a Phantom of the Opera and 2 of the 3 pop bumpers quit working. With my multi meter I can't find any problems with the diodes or capacitors...I believe the capacitors are ok, but not totally sure. I don't want to cut them out, order new ones, wait a week, and find out it's something else. Is it possible that transistors on the board are bad? Thanks for your help.
