Close · 74/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Airline GIM-9171A is a larger Japanese-built Airline combo targeting intermediate players in the early 1970s market. Its circuit features a solid-state front end feeding a tube output stage with a pair of EL34 or 6CA4-type tubes, yielding a fuller, louder performance than the smaller GIM models. The amp includes a spring reverb tank and tremolo, positioning it as a feature-complete gigging option within the budget category. Build quality improved over earlier transitional models, though it remains less robust than contemporaneous American-made amplifiers.
