Additional Details


The TC-378 was the third version of the popular 1971 TC-366, with a very similar set
of specifications and features.
Like its predecessors, it could be used in a vertical or horizontal
position thanks to the reversible slanted base.
Improvements included a line output level control, 2-position bias and 3-position equalisation switch for Fe-Cr, SLH and standard tapes, microphone attenuation switch, direct coupling between playback head and preamplifier and a retractable pinch roller for easy editing.
This deck had a fairly short production life and was nowhere near as popular as its predecessor.
Replaced by the TC-399 in 1978.
