Altec 831A Capistrano (circa 1960–1961)
Almost everything known about the Altec 831A "Capistrano" comes from period advertising and a brief mention in Audio (December 1960, p.47).
Altec guaranteed a frequency range of 35 - 22,000 cps. The enclosure measured 30 inches high, 47 inches wide, and 23½ inches deep. The Capistrano was picked for exhibition in the California Design show, and Altec made sure its own advertising said so.
Beyond these details, documentation is thin. It does not appear in the major Altec service manuals that have survived, and no original owner’s manual is known to be in circulation.
