Quad 4300
This archive's sources hold no verifiable documentation for a Quad-branded 4300. What follows is what the record does show.
Overview
This page shouldn't exist in its current form. The sourcing for this entry returned no documentation of a Quad 4300 audio product. There is no manual, no review, no catalog listing and no specification sheet. Every reference to a "4300" that turned up in research belongs to something else, and none of it is Quad.
The PDF manual indexed under this model number is a Flojet 4300 pump manual. It covers a self-priming water pump with a 12V DC or 115/230V AC motor, a fan/shroud kit, and a one-year warranty against defects in material and workmanship. It has nothing to do with Quad or audio. It is a pump. The troubleshooting section covers failure to prime, low flow and pressure, and pulsating flow. Nothing about tuner alignment or output stage bias.
The magazine review chunks don't help either. The most substantial reference is to a Marantz 4300 receiver, described in High Fidelity (October 1973, p.60) as a deluxe model at $900 whose tuner section could be separated from the main amp section for use with external amps or equalizers. HiFi-Stereo (December 1974, p.50) noted that unit's separate bass, mid-range, and treble tone controls, each a concentric pair for front and rear channels. A later HiFi-Stereo (1975, p.102) listing cites a Marantz receiver at $579.90 with walnut veneer cabinet, four VU meters, and SQ and regular matrix decoders. None of this is Quad.
A separate "4300" appears in Studio-Sound (July 1972, p.70) as a Chadacre Electronics 4300 Phase Simulator module, offered built and tested for £9.00 or in kit form for £5.50. It isn't Quad and it isn't a receiver.
Quad's actual catalog is well documented in this archive: the II and 33 amplifiers, the 44 preamp, the 405 and 405-2 power amplifiers, the 50 and 50E monoblocks, the FM, FM2, FM3, FM4, AM, AM2, and AM3 tuners, the ESL-63 and ESL-2805 electrostatic loudspeakers, the 67 CD player, and the FM Multiplex Decoder. No 4300 appears among them.
What This Means
Three possibilities exist, and the material at hand can't settle any of them. The first is that "Quad 4300" is a misattribution, a model number from another manufacturer (Marantz, Chadacre, Flojet) conflated with the Quad brand. The second is that a Quad 4300 exists but is undocumented in any source this archive has access to, which would make it vanishingly obscure. The third is that the designation is simply erroneous.
Writing specifications, production years, or a price for this entry would mean making them up, and the archive doesn't do that. If a reader owns a Quad 4300 and can supply photographs, a serial plate, or documentation, that would be welcome. It would be the first primary source on this model.
