A four-track stereo tape deck with two tape speeds (7½ & 3¾ ips) and a seven inch
reel capacity. The transport employed a 4/8 pole self-lubricating hysteresis synchronous
capstan drive motor and two eddy-current outer-rotor reel motors.
This was an auto-reverse tape-deck only with no internal amplification or speakers.
Two GX heads were used, a combined record/playback head and an erase head.
Equalisation was set to the NAB curve and frequency response was 30 – 25kHz 3db
using low-noise tape. 29 transistors and 15 diodes were used in the all solid-state design.
