You got me to check my KPA500, and with the yellow wire connected I showed at rest 73.7 v and 59.0 v key down, I changed to the next tap (red wire) and now it is 80.9 v and 65.9 key down, I think the amp has a shut down fault if the voltage goes over 85v I believe the assy manual says the the voltage should not go below 65v on key down. if it does you need to reduce the drive power to keep the distortion down.. my line voltage measured 240.2v so it seams the tap changed it about 7 v
