Hello folks. I have a 100B that seems to lose a little bit of gain/sustain periodically after a few minutes of playing. It happens on the Blue and Red channels where there is a slight drop in gain. It doesn't happen all of the time and seems to be intermittent. I have already replaced ALL of the tubes with new ones to rule that out. Any thoughts as to why this might be happening? Thanks, I appreciate the response.
