Hello

I have a Revox A77 MK3, sr: G170460, two tracks, with 7 1/2 and 15 ips speeds. I did not used it since some times.

I have a problem, when I turn it on, even wen I did not push any recording buttons, and without any input signal, the vu-meter are topping to the maximum and still topping to the maximum until I turn my Revox off.
