One more test when checking the output transistors is to go from the case which is the collector to the chassis. They should read open. If the case is shorted to the chassis you will have instantaneous fuse blown. They are mounted to the chassis using insulating washers and a mica film with heat sink grease. This usually can happen if someone over tightens the mounting screws.
