Hi, I think the problem may have something to do with the bass and volume controls. They are situated next to each other. I have just found that if I adjust the bass to minimum (least amount of bass) The volume control changes. You cannot turn the volume completely down, and lowest volume is at roughly the centre and the loudest volume is at the two extremes of the dial either side of centre. The highest volume being "turning the dial clockwise".Turn the bass to maximum and the volume behaves normally .Its too late to be messing with high voltage now, so will have a look tomorrow.
