Description

The TB491 was a quarter-track mono recorder with two-speed (3¾ and 1 ips) and a single Papst motor.
Fitted with Bogen heads it boasted a true Hi-Fi frequency response of 30-16,000 cps at 3¾ ips.
Features included superimposing, pause, monitor, and input mixing. A small internal speaker was incorporated but facilities were provided for connecting an external hi-fi speaker for superior reproduction. It was also available in a two-track version. The TB491 deck was used in the UK-produced Chitnis KM22 and KM33 recorders.
