Altec Lansing 749A
Almost nothing is documented about the Altec Lansing 749A. What little survives is a single classified ad in Audio (June 1979, p.112). The seller listed a 749A as an equalizer, rack-mountable, and threw in a sound level meter and tapes. They had paid $1,100 for the unit and were asking $500.
That one listing is the whole known record. No specifications, production years, circuit details, or user reviews have been found. The 749A shows up in an Altec driver and speaker cross-reference table as a linked entry, but that page gives no further description. Going by the original price, it was serious studio or pro-sound gear.
