9440's, classics, 800 W in a box when everybody else thought that impossible. Conventional wisdom said that much gain in one box could not be kept out of oscillation. A guy named Paul Rumbaugh proved them wrong. Made ca. 1978-1982. It cost $100 in parts and labor to change the light bulb illuminating ONE of those VU meters - t.u.
