The remaining chunks in the period record, from Audio (October 1964 through December 1964), refer only to the Altec 470A amplifier and 550A power supply. They say nothing about the 852A. The research turned up no production years, original price, cabinet type, crossover details or any other specs. The 852A is a mostly blank entry in Altec's loudspeaker catalog, known only through this one fragmentary listing.
