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.
