Description

The TC-377 was the second version of the popular 1971 TC-366, with a very similar set of specifications and features. Like the TC-366 it could be used in a vertical or horizontal position thanks to the reversible slanted base.
The main improvements however (other than a slightly snappier styling) was the utilization of hard wearing ferrite & ferrite heads and servo controlled tape tension. A unique electronic detail of the 377, features the preamp signal going directly to the transistors without running through capacitors (superior design)

Another unique feature (which you may or may not like) ‘TMS’ – or ‘Total Mechanism Shut-Off’ – which turns off the machine completely at the end of the tape.
This deck had a fairly long production life and was still selling in the USA in 1979 ($450 – Stereo/HiFi
Buyer’s Guide).

Apparently this machine was designed to record and play back encoded SQ (Stereo Quadraphonic) signals. We are not aware of any SQ encoded prerecorded tapes so perhaps this refers to taping quad SQ LPs, which were available at the time.

The 377 was sold in Japan as the TC-6360-A and a rare Quadraphonic version –  TC-6364
