Kenwood KA-900
(1981 - 1982)

Smaller sibling to the KA-1000 - only with a single PT integrated power supply and a smaller heat-pipe. The rest is nearly identical.

With High-fT transistors, a DC...400kHz bandwidth, 2x 80W (20Hz...20kHz), a slew rate of ±120V, a 0,9µs rise-time and a 500 damping factor at 100Hz), the KA-900 was a tight and futuristic way to start the 1980s... even if made of plastic.
