Sony TC-377 Reel-to-Reel Tape Deck (c. 1972)

Not much information on the Sony TC-377 has survived. No full review or service manual has surfaced in the archive's holdings. Almost everything known comes from Sony's own advertising and a couple of passing press mentions.

Sony/Superscope launched the TC-377 at $289.95. The ad ran in Audio (October 1972, p.44) and called it "a brand new angle." It was a three-head tape deck on a reversible slanted base, so it could be angled correctly whether you ran it horizontally or stood it vertically. The same campaign sold it alongside the TC-366, which carried TMS. Whether the TC-377 shared that feature is not documented.

The only bench-style data to surface comes from HiFI-Stereo (June 1973, p.40). It measured line input sensitivity at 48 mV and microphone input sensitivity at 0.14 mV. The reviewer noted that driving the mic inputs at full gain added noticeable hiss and knocked the signal-to-noise ratio down by 5-8 dB. That is unremarkable for a deck at this price point.

By March 1977, a column in High Fidelity (March 1977, p.15) could refer to the TC-377 in passing as a "cheapo" reel deck. It lingered in the market as an inexpensive, no-frills option rather than a flagship. When production actually ended isn't recorded.
