It looks like my post hasn't stimulated any interest but in case it does later I've a few things more to add. I called the seller to get info on bias adjustment because there is no information on this amp anywhere. He explained that it is auto biasing so, although I realize there are some on these forums that don't like auto biasing, it's at least one thing I don't need to concern myself with. Another thing I neglected to mention is that it has right and left balance controls which leads me to suspect that its design is that of a dual monoblock amp.
Im beginning to believe that it may have been a DIY kit adapted into this massive chassis. Although it has point to point wiring, it is mounted on a fiber circuit board which, at first glance of its photo, makes it look like the top of a PC board. Even if it sounds like a potentially very poor choice to have bought this thing, I would like to hear what you think. If that evaluation turns out to be the case and that I've way overpaid I'm still happy because of its wonderful sound.
