Revox b77 Volume Knob: is it normal?

lucianop · 30th January 2012

Hi friends, here I am with my lovery Revox b77. I bought it from ebay. Everything seems to work perfectly but I'm not sure about the big volume knob:
when I move it, it doesn't seem to affect output level, exept headphone output volume. So, the title request: is it normal?
thanks,
Luciano

Yes, it is normal.
The volume knob only affects the headphone output.
The manual says:
"The tandem potentiometer VOLUME varies the level for headphone listening.
The innermost potentiometer acts on the left channel while the right channel is controlled by the potentiometer on the front.
Both controls are connected via a slip-clutch, thus permitting their individual adjustment to achieve the desired balance."

So: Your B77 is working correctly.
