Sony's first three-head cassette recorder, unveiled at about the same time as the other first one - the better remembered Nakamichi 1000.

The TC-177SD was sold in Japan under the TC-6150SD moniker, cost 158,000¥, and remained the brand's top deck even after vertical ones were introduced and was just as expensive as the professional TC-164SD portable.

Azimuth control works with an adjustment wheel between the tape compartment and transport keys and a LED confirmation placed between the meters.
Center, the drive is a closed-loop dual capstan feeding three F&F heads.

What is difficult to grasp with this image or any other for that matter is the size and weight of this recorder - and it pumps 52W off the wall, too !
