Quad 18

Nothing is documented about the Quad 18. The Archive's research has turned up no advertisement, period review, service manual, or specification sheet naming an "18" model. The product's type - amplifier, tuner, or otherwise - is still unidentified. The surviving period literature for Quad in this era centers on the Quad II amplifier and the AM and FM tuner units. Audio-Collection (1964, p.18) lists the AM.II tuner's output as 100 mV at 5,000 ohms and a price of £24, but no "18" appears anywhere alongside it.

"18" could be a catalogue shorthand, a misprint, or a variant designation. That is speculation, not documented fact. If a reader holds original material naming the Quad 18, the Archive would welcome the documentation.
