I worked on a pair of these amps, had bias problems. Wow they were annoying. Really nice for impressing your friends, or heating up your listening room, or making your electric meter spin, if you are into that. I was not impressed. I felt a modified Dynaco ST70 was way more listenable. The output transformers were really not rated for full bandwidth at full power. Circuit was not very nicely done. I would give it a solid "meh" on my audio scale. You can do a lot better for a lot less.
