Description
The
TK 147 was a solid state, 4-track stereo recorder with a single speed
of 3¾ ips and a 5¾ inch reel capacity. It was basically the
stereo version of the TK 146 and at the
time of its release was described by one tape recorder magazine as ‘the
lowest cost’ quarter-track machine available.
A single motor and two heads were incorporated
into the design, other features included automatic recording level and
auto stop.
Mono audio output was 4 watts into a single
internal 7¼ x 3¾ inch speaker, stereo playback requiring an
external speaker and amplifier.
