Peavey CS 800 Amp Rack MountThese are Peavey CS 800 Professional Stero Amplifiers. They are designed to be rack mounted. We have 3 of these for sale. We used these Amps in our bar for several years. During remodeling we upgraded our Amp racks. These were working pulls at that time. I have plugged all of them in and turned them on. They all seem to power up just fine. However I have not hooked any speakers up to them. These are being sold as is.
