The Sound Power of the 1970s

The Phase Linear 400 is a class AB stereo power amplifier designed by audio electronics engineer Bob Carver in 1970. The unit is rated at 200 watts R.M.S. continous power per channel (8 ohm impedance), and 400 watts R.M.S. continous power per channel into 4 ohm impedances. While the semiconductor enhancements since 1970 have yielded cleaner devices for high-end audio, in its day the Phase Linear 400 was the amplifier of choice. Even today the Phase Linear 400 continues to operate flawlessy, a testament to the craftsmanship of the era. If you come across one in the future, get it. Your subwoofer will love you.
