The well-known reliability of the Revox A 77 is a result of a professional design concept which successfully combines the advantages of a solidly constructed tape transport mechanism with the advantages of an advanced electronic circuit design. A 3-motor transport mechanism with electronically regulated capstan motor and solenoid operated servo-brakes possesses few parts which are subject to mechanical wear. The use of a diecast motor chassis and head support ensures that a high degree of mechanical precision and long term stability are maintained, even under excessively heavy use. The mechanical and electronic properties thus complement each other in a most successful way.

Mechanical:
Tape Transport Three Studer eddy current motors. Electronically governed capstan motor. Electronic speed change. Solenoid operated via 3 relays.
Tape Speeds 3.75 and 7.5 ips ± 0.2%
High speed Version: 7.5 and 15 ips ± 0.2%
Wow and Flutter max. ± 0.04% at 15 ips
max. ± 0.08% at 7.5 ips
max. ± 0.1% at 3.75 ips 
Tape Slip Less than 0.2%
Reel Diameter Maximum 10.5″ 
Minimum hub diameter 2 3/8"
Forward / Rewind Fast winding time for 1800′ is 92 seconds
Tape Heads Three ( Separate precision erase, record and playback heads ) Patented ‘True Radius’ design ensures excellent S/N ratio and head wrap
Operating Position Horizontal or Vertical
Electrical:
Monitoring Individual stereo record and playback heads with separate preamps, plus separate record and play circuits permit full source-tape monitoring.
