Additional Details

Description

The TR52 was produced in various versions, single channel full or half track (TR52/1) and two channel
(TR52/2).   In addition, each variant came in two versions depending on tape speed, “C” for 3¾ and 7½ ips and “D” for  7½ and 15 ips.  The model pictured here is a TR52/2C
Marketed as a professional model, record characteristics were set up in accordance with CCIR recommendations and separate record and replay amplifiers and heads permitted “off-tape” monitoring.
A single motor connected to the capstan assembly via a flexible coupling also provided power for the take-up, rewind and wind-on facilities.
