Ampex A692
A compact speaker-amplifier built to sit beside an Ampex tape machine - and priced, in 1968, at a hundred dollars used.
Overview
The A692 makes more sense once you know what it was paired with. Ampex built it as a speaker-amplifier - a self-contained powered speaker - to go with the company's tape equipment. The clearest evidence is the cover of the November 1957 issue of Audio, which shows photographer Donald Wolter relaxing with an Ampex Portable System A 122-P and "the two matching speaker-amplifiers, Model A692-P." So the A692 was not a standalone hi-fi product. It was the amplification-and-reproduction half of a portable tape system, sold in matched pairs to flank a recorder.
It is not a receiver, not an integrated amp in the conventional sense, and not a bookshelf speaker you'd buy on its own merits. It's a system component. It turns an Ampex tape transport into something you can listen to without a separate amplifier and speakers.
The A692 shows up repeatedly in the period's classifieds. A 1968 equipment listing in Audio (March 1968) offered an "A692 Amp. spkr." at $100, alongside an A122 recorder at $100 and a pair of 2010 amplifier-speakers at $120 each. All were described as being in gray portable cases and in excellent condition. A decade after introduction, then, the A692 was trading used at a hundred dollars, roughly on par with the recorder it was designed to serve and a bit below Ampex's larger 2010 speaker-amplifiers. The gray portable cases fit the portable-system concept the 1957 cover photo advertises.
The A692 also turns up in broadcast classifieds. A 1961 "For Sale" notice in Broadcasting advertised, among a batch of professional gear, "1 Ampex A692 monitor speaker and amplifier" being sold along with a Grampian cutterhead and a pair of Sigma mixers. That a station or studio would have one on hand suggests the A692 found use beyond the living room, as a monitor speaker in production settings where an Ampex tape machine was already around. It's modest evidence, but it fits: the A692 was the speaker that went where the Ampex recorder went.
The surviving documentation does not give the hard engineering. No power rating, no driver complement, no frequency response, no dimensions or weight appears in the sources available here. Collectors chasing a spec sheet will have to find an original Ampex owner's manual or catalog page, because the period magazines treat the A692 as a known quantity and never spell out its numbers. What can be said is narrower: it was a speaker-amplifier, it was sold in matched pairs to accompany Ampex portable tape systems, it was offered used at $100 in 1968, and it came in a gray portable case matching the rest of the system.
The A692 is mainly a system accessory - the correct companion for an A122 or similar Ampex portable, and a way to complete a period-correct setup. Its appearance in both consumer-audio and broadcast classifieds suggests it was competent enough for monitoring work, but the documentation here doesn't support claims about how it sounds, how much power it makes, or how it compares to anything else. Anyone restoring one should expect to source or reconstruct the matching recorder, and should treat the gray portable case as part of the package.
