Various Altec manufacturing and test facilities
Photo 26 - Manufacturing multi-cell horns
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.
Microphone test area in Anaheim - t.u.
Electronics A-frame in Anaheim - t.u.
Anaheim, test station at the end of the A-frame - 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.
Model 19 home stereo speaker, still made in the early 80's. This one
has the 811B horn and a custom crossover - t.u.
Military applications of Altec products
Seven compression drivers, seven re-entrant tone arms, one horn.
Contractors were still begging for this contraption as late as the 1980's - 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.
