The 500 is the first amplifier of SA. The 500 and 900 (1981) were unofficially called "SA 500A" and "SA 900A". The B-series (1983) is the same as A-series, but has balanced inputs, individual power supplies and ground lift switch. The C-series (1985) is based on the B-series, with improved "high-speed" design (different transistors), improved on/off switch and handles (front and rear). The SA 450 (1987) is a single-channel version of the SA 900C, with selectable line-voltage (70V/100V). The SA 500 and SA 900 series were produced between 1980 and 1990.
