Description
Perhaps trying to make up for lost time and to show that Technics was in fact a real contender in reel to reel tape recorders, they released 7 models in 1978, first the RS-1500 and shortly thereafter the RS-1506, RS-1520, RS-1700, RS-1800, RS-10A02 “R&B Series” and a smaller Japanese market specific recorder, the RS-777.
The RS-777 is an auto-reverse quarter track track deck using the RP-2R2P headblock. It has the Isolated Loop tape path developed by Technics with really low wow and flutter (.018%) that also keeps down modulation noise.
A a very smooth and stable tape path using a large 34mm capstan and 2 pinch rollers combined with an electronic tension control system completes this transport. Tape tension on the Isolated Loop tape path is low compared to many other machines, so for those using older tapes with rippled edges, this may not be the ideal.
A Quartz-Locked Direct-Drive Capstan Motor completed the well-designed assembly.
Logic controlled electronic braking, which applies reverse torque to the motor prior to deploying a mechanical brake, results in very smooth transition between function selections and virtually no tape stretch.
This model was unique in the lineup using two colour digital fluorescent meters similar to the Sony 880-2 and had a pitch control that was variable by 6%. They also added a cueing feature.
