This circa-1976 Multivox amplifier, possibly identified as a W7591 model, uses the 7591 output tube common to mid-century American combo amplifiers. Multivox was a New York-based importer and manufacturer that sold instruments and amplifiers under various brand names including Premier. The 7591 tube gives these amps a distinctive warm, mid-forward character typical of late-vintage American designs.
