Additional Details

Description

Clarke & Smith were
one of the few companies to use the Wright and Weaire tape deck mechanism,
Vortexion and more famously, Ferrograph are the only others that spring
to mind.
C & S recorders were mainly produced for sale to education authorities,
universities etc. Record and playback amplifiers were transistorised,
and they had facilities to connect to 70-100V lines for use through public
address systems.
The TR-634’s wooden cabinet was very substantial, bringing the overall
weight of the machine to nearly 50 lbs (22 kg) and an extra long carry-handle
was fitted to enable two people to carry it.
