Good news...I think. I didn't know the Allegro has a fuse... it blew. I can't read the amperage, looks like 170 and then an upside down 50 which makes no sense. Hopefully the schematic shows amperage. I could have saved myself a lot of amp-removal work if I had studied first. Oh well. Lesson learned. Hopefully the root cause of the blow was the bad tube.
