Additional Details


From the 1955 service manual: The “Reporter” TK 12 is a dual track recorder able to record and play back in both directions.
It operates at the two tape speeds of  3¾ & 7½ ips. The Electro-Magnetic change over from track one to track two position takes approximately 3 seconds at 7½ ips and less than one second at 3¾ ips
A precision built “clock type” position indicator is fitted to enable the exact location of a recording.

The TK 12 switches itself off automatically at the end of each reel of tape by means of metal foils.
This was a very similar machine to the TK 9  but whereas this was a twin speed machine, the TK 9 had only the single tape speed of 3¾ ips.
As with the TK 9 and the TK 820, two sets of record/playback heads and erase heads were fitted to this early auto reversing recorder.

Additional Info

Rewind speed: approximately 1½  minutes / Audio output power: 2½ watts / Tone controls: bass and treble emphasis (one control) / Speaker(s): permanent magnet elliptical / Weight: 28 lbs (12.7 kg) / half-track mono
