Revox B77 HS
The B77 MKII tape recorder was built from 1980-1998. A true classic and milestone in the audio world, like its predecessor the MKI. The 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 us completely overhauled and refurbished. The impressive end result is a product as good as new.
