DESCRIPTION

The TC 850 was a semi-professional three-motor, four head tape deck with a 10½ ” reel capacity.
The recorder could record in half-track stereo, but thanks to the extra playback head, quarter-track stereo playback was possible.
All transport controls were servo-controlled, which resulted in a seamless transition between transport modes. The recorder was considered ‘easy to use’ by reviewers.
This was not a cheap machine, in 1974 it cost almost twice as much as a Revox A77 so it is fairly easy to see why not many were sold.
