Additional Details


The Sony TC 366-4 was a quadraphonic version of the TC 366 and had many of the advanced features this popular two-channel stereo deck including automatic total mechanism shut-off, hyperbolic heads which required no pressure pads, tape/source monitoring and more.

Unlike its three-speed stereo brother, it only featured the two higher tape speeds of 7½ and 3¾ ips. It was however, more than double the price, although less than some of the other 4-channel stereo tape decks of the time. Aimed at the budget-minded music lover seeking full four-channel record and playback this recorder didn’t really take off and is quite rare today.
