Search for SB-220 instead. You should drown. It was a very popular amp. http://www.somis.org/ for a start is Rich Measures' page - he wrote a series of articles in QST about the 220 some time ago, which as I remember started a furore with disputations from many major amplifier designers of note, but at least it's a start.
