Revox B750 MKII Amplifier
Quote studerundrevox.com.
"Thus, the ReVox B750 became the first integrated amplifier in the "normal" power class with fully complementary, balanced power amplifiers, low overall negative feedback and extensive electronic protections for power amplifiers and connected loudspeakers.
With the ability to cleanly resolve even the most difficult dynamic jumps, the B750 had what it took to be a potent and highly musical control center with six stereo inputs. The preamplifiers and power amplifiers could be separated and cleared the way to loop in an equalizer, for example.
Two tape recorders could be checked by means of a back-tape control and directly switched for tape copies. The tone control network contained beside treble and bass controls a further one for presence, with an altogether finer gradation (2 dB steps).
The B750 was built in MKI and MKII versions (see pictures) in the period between 1977 and 1982."
Visual Condition:
Generally good condition with normal partially visible signs of use over the years.
Please look at the pictures, they are part of the item description.
Technical condition:
The device works. However, since it has not been overhauled, we can not say and guarantee how long the device will run.
The device was not overhauled and is therefore offered as a hobbyist device without warranty from us.
