I have 2 like new Bose business music amplifiers ,
they are the AmPlus 100 and 50.
they include all terminal plugs , 120v plugs, and amp rack brakets. I do not have volume controls but are not that expensive. You can turn up volume from your reciver you do not need to use volume controls.
Retail is over $700 each.
I will take $400 for both.
They both are 100% working and mint.
