Anaheim shop. Probably these cells have the spray-on damping and are not
tar-filled. The multicell solderers were the highest-paid craft anywhere in
the Altec plant - t.u.

Electronics lab, Anaheim, late 1970's or early 1980's. The unit on the
bench with the four transistors in the heatsink was a bi-amplifier made for
the A7 - t.u.

Outside the anechoic chamber. What looks like electrical conduit on the
wall behind the racks (that's the wall of the anechoic chamber) is actually
a couple of plane-wave tubes - t.u.

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.
