Upon further inspection, looking at the line 6 return form, this thing "worked for 24 for hours, then made low end hum, then died"
The problem was traced to the 0.5A fuse and V7 in the power section blowing. These were replaced. Now, I've looked at the fuse, and whad'dya know, its blown. I should probably mention that there were thunderstorms out there so it could have been a power spike.
