Close · 73/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Airline GVC-9017A is a budget department-store tube combo amplifier sold through Montgomery Ward stores in the 1960s, manufactured by Valco or Kay under the Airline brand. Like most Airline amplifiers of this era, it offers tremolo and a surprisingly characterful tone despite its humble origins. The GVC series was Airline's mid-tier guitar combo line, offering more features than entry-level models at a price accessible to young American players.
