Sherwood S 9900A (1966–1968)
A solid-state stereo integrated amplifier produced in the late 1960s, rated at 40 watts per channel.
Overview
The Sherwood S-9900A is a solid-state stereo integrated amplifier made around 1967, with production running from 1966 to 1968. It was built in Chicago, and it was Sherwood's move into higher-power solid-state designs. It puts out 40 watts per channel into 8 ohms in stereo mode and has 23 silicon components in its complement. Documentation is thin, but surviving units suggest it was built to last and to sound good. Some owners say it still sounds pretty nice today.
