The TC-777 was (according to SONY) Japan’s first all-transistorised tape recorder. It was a semi-professional, half-track mono recorder with three heads, three motors and two operating speeds.
The controls had a very solid feel about them and for 1961 this was a sophisticated piece of equipment. The tape transport mechanism was mounted on a die-cast aluminium block to maintain precision tolerances.
Replay characteristics were to NARTB specifications and the transport controls were via solenoid-operated push-buttons with an optional remote control facility.
The recorder underwent minor modifications in 1962, becoming the TC-777A. However, these machines were very expensive (almost 30% more than a stereo Revox G36) and as a result didn’t sell very well outside of Japan. The 1963 stereo version, TC-777S fared a little better.
