A kit-form quarter-track “professional” stereo tape deck with three hyperbolic heads
and two speeds, 7½ and 3¾ ips. The transport unit came pre-assembled and the proud new owner could assemble the solid state modular circuits.
The deck had two separate motors, a precision capstan motor with flutter-filter belt drive and a separate take-up motor.
A single rotary knob controlled tape motion and six illuminated panels (green for play and red for record) indicated mono record/playback or stereo. Record level was indicated via twin VU meters and other features
included sound-on-sound and echo at the flip of a switch, flip-up head cover for easy editing and cleaning, a three-digit tape position counter, cue control, microphone and auxiliary input mixing, built-in stereo headphone preamplifier for monitoring. automatic end-of-reel shutoff and vertical or horizontal operation. There was also a built-in 1kHz bias test oscillator.
Total harmonic distortion: less than 1.5% at “0” VU / Bias frequency: 80kHz / Semi-conductors: 17 transistors, 6 diodes / Rewind speed: 1200ft in 60 seconds forward, 90 seconds rewind / Inputs: mic – 3000 ohms, 1.5mV, line – 50,000 ohms, 100mV / Outputs: playback – 250 ohms, low impedance stereo headphones / Equalisation: 7½ ips, NAB – 3¾ ips, EIA
