Additional Details


Although Sony had produced a pretty decent number of reel to reel tape recorders since the early 60s, when the cassette came along, they put a lot of their focus in that direction and reel to reel seem to fall a bit by the wayside. When Sony did show up with a new model, it was usually mid to high end. The introduction of the  TC 766-2 was a semi-professional 2-track recorder, designed for more serious users. It has a lot of similarities to the Sony TC-765 which was a 1/4 track low-speed machine with three heads. This half track model featured a quarter track playback head which was switchable. Both machines used the Super durable Ferrite & Ferrite Heads.
Features included logic controls, closed-loop dual-capstan drive with AC servo control, 4 heads and remote control option. Relative to the  competition in this price point, its features were a bit sparse but it had all you needed to do get the job done.

From the promotional material – The SONY TC-R7-2 achieves an incredible wow and flutter of 0.018% (WRMS) at 38 cm/s and 0.04% (WRMS) at 19 cm/s. This is achieved via a Closed Loop Dual Capstan Tape Drive System. One capstan extends from the motor shaft itself, eliminating intervening gears that can hamper speed accuracy. The other tape drive capstan connects through an extremely steady belt-drive inertia wheel. For a “mirror image” of the original signal, Sony’s exclusive Phase Compensator Circuit comes closest achieving this by rectifying phase distortion and producing sound quality virtually identical to the original source.
