    I have one of these on the bench with some nasty phase distortion in the output. Been looking for some schematics as well. From what I've heard the company changed hands and many of the documents on the older equipment are no longer available.

    When you say it shuts down, what exactly happens? Is it blowing a fuse? Is the power transformer getting really hot?
