Stuzzi Tricorder 578 W

A compact half-track mono recorder with three speeds, named for being an early adopter of the ultra-slow 15/16 ips speed which gave 12 hours of continuous recording, alongside an exceptionally well-designed tape drive that kept wow and flutter low even at that speed. Features included mixable microphone, pickup and radio inputs, interlocking push-button controls, superimpose facilities and space for a third playback head.
