Hello all. 
I purchased a Woburn II online that was described as "new". 
first, the back of the unit has no writing on it al all. 
just black.  
As soon as I plug it in it powers on. 
Pulling the power lever does nothing.  
both Bass and Treble knobs work. 
The volume knob does not. It shows it's at 75% volume. 
the button that changes from Bluetooth to other inputs is not lit and holding it down does nothing. 
I tried a hard reset but no change. 
Any help would be appreciated. 
thank you in advance
