The Quad 33 production run was 1967 through 1982, replaced by the Quad 34.
The Quad 303 ran 1967 through 1985, replaced by the Quad 306.
The Quad FM3 ran 1971 through 1982, replaced by the Quad FM4.
Quad was relatively late in introducing a solid-state FM tuner. The initial iteration of the FM3, with the TAA661B and MC1305 ICs, was still a "transitional" design, although less so than some of those that preceded it, such as the Rogers Ravensbourne and Ravensbrook, Leak Stereofetic and Sugden R21/R51. With the 3rd iteration, CA3089 and MC1310 ICs, Quad had landed upon what became an "industry standard" basic configuration.
Cheers,
Steve
