Not much is known about the SF90 or "Staggered Four (channel) 90 watts" other than its one of a few most rarest amps ever manufactured by Soundstream. Built around 1985, this was some of Nelson Pass earlier work he did for Soundstream. It was noted this amp retailed for around $350 and may have only been available overseas.
