Description
The TC 651 was an auto-reverse (playback only), quarter-track stereo deck with tape speeds of 7½ and 3¾ ips. Three separate motors and four heads were employed (erase, record, play and reverse play) with reels of up to 7″ being accommodated.
Other features included SOS, tape/source monitoring, normal or SLH tape selector switch, line/mic mixing, adjustable headphone output and ‘feather-touch’ solenoid transport controls.
Second from the top in the Sony range in 1972 (this distinction went to the TC 850-2), the TC 651 retailed
in Great Britain for £272.95
