Quad 33 / 303 / FM3, 1967
Control unit, power amplifier, FM tuner,

A near-perfect example of a classic late 60’s design.

The 33/303 were the first transistorised produced by Quad. The amplifiers introduced a new ‘Triples’ output stage that solved many of the problems, including overheating, of earlier transistor designs.

Original operating manuals for each component.

Design Council Award, 1969.
