Curious if you guys can help me. Went to one of my consignment stores and found some old audio equipment. An Adcom gfa 555 amp for 99 bucks, a Velodyne ULD15A7 ULD Series II Power Servo Controller ( minus sub) and a Adcom ace 515 AC enhancer. I picked up a Sony AM/FM stereo tuner 730es for 10 bucks. All this was dropped off buy the same person as there were notes on the wires and such stating how everything was connected. Just curious if any of the other stuff is worth going back and getting. I'd probably resell but curious if the older stuff is even worth grabbing
