The plugs come out then you flip over plug and insert wires into their respected terminals then tighten with the now exposed screw heads then re-insert plugs into amp....//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
thanks for all the responses, this was an ebay find....i just hooked it up....things aren't looking to promising. The low impedence light is on with power light, its sucks an *** of power and is making an electrical hum somewhere around what looks to be the power supply(donut shaped coil). and the hum goes to the speakers as well with no music.
OP pm me if you don't mind driving to Charlotte, NC to have it looked at/repaired......I know a guy who is a wizard with those PPI Art Series amps. He sold them way back in the day & knows them very well.
