Dive into the World of Reel-to-Reel Tapes with the Revox B77 MkII Open-Reel Tape Recorder: Completely Overhauled and Reconditioned Unit Features Tone Motor Control, Revised Audio and Drive Electronics
The B77 MKII tape recorder was built from 1980-1998. A true classic and milestone in the audio world, like its predecessor the MKI, this completely overhauled B77 MKII is equipped with a built-in sound motor control (Vari-Speed Control) and revised audio and drive electronics. As a manufacturer, we have been reconditioning our Revox units with original spare parts for decades. You will receive the B77 MKII from Revox completely refurbished. The impressive end result is a product as good as new. The main difference to the MKI is that the B77 MKII is equipped with a built-in tone motor control (Vari-Speed Control) and revised audio and drive electronics. Each unit comes with a certificate and two-year manufacturer warranty.
In addition to the standard version with speeds of 9.5/19 cm/s, the following models were available: B77-HS with 19/38 cm/s (High Speed), B77-LS with 4.75/9.5 cm/s (Low Speed), B77-SLS with 2.38/4.75 cm/s (Super Low Speed for monitoring tasks), B77-AUT0 with automatic recording start as well as three versions with additional pilot head for simple to sophisticated slide projector control. B77 synch tape recorders had a clock track amplifier for professional synchronous recording from the recording head. Finally, the B77-DOL offered separate Dolby TM-B processors for recording and playback (i.e. "dolbysed back-band" control) for the highest noise levels (19 cm/s, half-track, better than 74 dB).
