Pioneer SA 700 (1970–1971)
A solid-state integrated stereo amplifier from Pioneer’s early 1970s “Famous Series.” It is noted for its build quality and warm phono performance.
Overview
The Pioneer SA-700 is a solid-state integrated stereo amplifier, built from 1970 to 1971. It belongs to Pioneer’s “Famous Series” and was designed for high-fidelity sound in the early days of home stereo. The front panel is brushed aluminum, and the side panels are original rosewood. It has two phono inputs and can drive two sets of speakers. A matching tuner, the Pioneer TX-700, came out alongside it, so the two were clearly meant to work as a set.
