From the 1954 service manual:
The “Reporter” TK 9 is a portable machine capable of recording on quarter-inch tape. The machine is a dual track recorder and is able to record and play back in both directions.
It operates at a tape speed of 3¾” per second.
The Electro-Magnetic change over from track one to track 2 position takes
less than one second.
A precision built “clock type” position indicator is fitted to enable the exact location of a recording.
The TK 9 switches itself off automatically at the end of each spool of
tape by means of metal foils.
Very similar to the TK 15/3D which had two speeds and three speakers
