Eric, my amp has a passive volume control, and the whine scales with the
setting. I normally have it at maybe 40%, and at that level I can only
hear it with an ear very close to the tweeter. At 100% it's
considerably louder, although still only audible pretty close to the
tweeter.
This is as ex

Its on BOTH of my SB3s on the audio side only, one channel only.
There are three peopl
I have this too, although it's too faint to be noticeable normally. Try
turning up your amp's volume all the way and put your ear close to the
right tweeter with the SB idle.
I suspect all SBs do this, it's just that some people have greater gain
on their amps, more sensitive speakers/headphones

I tend to leave the amplifier at half-way, unless I'm trying to destroy
the windows. I use the SB3 analogue outs and adjust the volume with th

My problem is exactly correlated to brightness display as indicated in
my post.
I am going to add -20dB attenuators becaus

Bingo! A shiny pint for the man in lead boots and concrete trilby!
Thanks very much -- it was the display. Turning it off kills the noise.
I think I'll probably make the display
You could try dimming the display - is the sound correlated with the
brightness setting?
Another thing is to move the SB around while listening with headphones.
Does the sound change depending on where the SB is located?
