Description/comments: Introduced in 1972, the 400 amplifier was probably Phase Linear's most popular amplifier due to its more than adequate 200 watts per channel and reasonable price. The 400 featured twin output meters, six output transistors per channel, plus two drivers per channel (right below the output transistors) and massive heatsinks. Power Amplifier
