ReVox B77 MKI 2-Track 7.5ips Tape Reel Recorder Player

Description: ReVox B77 MKI 2-Track 7.5ips Tape Reel Recorder Player The B77 was available in quarter track or half track and was a two speed recorder, quarter track 3.75 – 7.5 ips or half track 7.5 – 15 ips. Studer-Revox manufactured their own capstan and motors. These motors were electronically controlled and are given higher starting voltage slowly reducing to regular voltage for fast starts and smooth tape handling.The capstan motor employs a precision-machined set of teeth at the circumference of its motor. As the motor turns, these teeth create a series of pulses that are read by a tachometer head and whose rate is compared against the frequency of a stable internal oscillator. In this way, even very slightest speed variations are immediately detected through a fast-acting servo system. To reduce wow and flutter even further, the direct-drive capstan shaft is machined to an accuracy of one one-thousandth of a millimeter, is hard chrome-plated and is artificially aged during the manufacturing process to ensure long-term stability. A 4th head could be added for audio-video control or slide-projector synchronization.The Mk II version is the same as the Mk I except it adds a speed adjustment knob under the built-in editing block.
