Hi Pete, With fuse blown check HOT collector, if B+ there, power supply probably ok. There have been problems with the audio panel soldered to the main board. There is a small two wire cable from the SMPS that plugs in near the metal box audio panel, unplug it. With jumpers hookup another fuse and try set. Another point don't get to involved as these are the sets with the bad A68AGD picture tubes.
