Sony Sterecorder 500
A four-track stereo tape system whose speakers fold into the lid of the carrying case — and whose $399.50 price bought a complete rig, microphones included.
Overview
The Sterecorder 500 is a complete four-track stereo and mono tape system, and the detail that sold it — the one Sony led with in every advertisement — is the pair of acoustical cone suspension speakers built to combine into the carrying case lid. Detach them and they run out on 15-foot leads for proper stereo spread; snap them back and the whole machine travels as one package. It was a genuinely clever piece of industrial thinking for the period, and it's the reason the 500 reads as a self-contained system rather than a deck with accessories bolted on.
That completeness is reflected in the price. Sony's own advertising billed the Sterecorder 500 at less than $399.50 complete with two F-87 cardioid dynamic microphones — so the buyer wasn't hunting for mics or speakers after the fact. Audio (November 1963, p.9) ran the same figure in the launch copy, and HiFi-Stereo (October 1963, p.16) repeated the under-$399.50 package with the two F-87s. For a four-track stereo machine with its own speakers and microphones, that was the pitch: walk out with everything.
Operationally, the 500 was built to be flexible. It records and plays back in four-track stereo or mono, and it runs either vertically or horizontally — a real convenience for a machine this size. Microphone and line mixing are on board, so a user could blend inputs rather than being locked to a single source. There's sound-on-sound for overdubbing, two VU meters for level watching, and a pause control for clean starts. A contour switch, automatic shut-off, and automatic tape lifters round out the convenience features. FM stereo inputs and "Multiplex Ready" status meant the deck was prepared for the coming FM multiplex era — the advertising made a point of it, and every Sony Sterecorder in the line carried the same claim.
The transport is where the 500's ambitions show. It uses a hysteresis-synchronous drive motor with a dynamically balanced capstan flywheel — the kind of drive arrangement aimed at steady speed rather than the cheapest possible mechanism.
The Sterecorder 500 sat near the top of a deep Sony tape lineup. The same 1963 advertising spread placed it above the Sterecorder 600, a three-head unit with tape and source monitoring and sound-on-sound at less than $450, and well above the compact Sterecorder 200. The 500's own niche was the complete-system buyer who wanted stereo, speakers, and microphones in one purchase without stepping up to the monitoring flexibility of the 600. By the time the 500-A appeared in 1965 advertising, the line had moved on to a new 2.5-micron-gap head promising flat response from 40 to 18,000 cps ± 2 dB — a reminder that the original 500 was a transitional machine in a fast-moving product family.
What the 500 represents today is a specific moment in home tape: the point where a stereo recorder became a piece of furniture-adjacent, self-contained audio gear rather than a component for the hobbyist's rack. Anyone chasing one should confirm the speakers, the microphones, and the lid are all present, because the package is the point.
