Sony's last super-deck, or super-consumer deck...
The TC-766-2 is the 2-track version of the TC-765, also topping the latter with 38cm/s speed.
Apart from that, visually and internally identical : same F&F heads, same FG-Servo AC motors, same DC rec/play FET amps, same everything and even a tiny "rec mute" switch very conveniently placed... at the back.
Originally released in Japan as TC-R7-2, selling very well there just as elsewhere on the planet.
Sales-wise not up to the TC-755 series but there are many many 765, 766-2, R-6 and R7-2 still playing and recording worldwide.
Truly excellent decks topping with magnificent looks, too.
Since posting this page in 2005, I have finally found and bought the original, lavish and 32x32cm japanese catalog for the TC-R6 and TC-R7-2 - it took... six years !
