I was able to use a car trim removal tool to carefully get the plugs out. Changed valves and that was not is source.

Clip of the bizz. Will have to turn it up a little. It's more quite in the clip than live.

Have you tried it in a different electrical socket ? 
Mains hum perhaps ? 
Presumably it makes that noise with no input ?

Yes, same noise.

But no noise if nothing connected in the input. 

Does get louder if output is raised. Never goes away even is output is all the way off.
