I recently acquired this from an estate sale. The guy said it was his fathers. He said he thought it worked but was unsure how to hook it up. He said it has never had any work done on it. I only tried the the tuner input with left and right speakers and It does work and sounds pretty nice. surprisingly only a few scratchy controls and the little panel with the rca inputs is a little loose. obviously it needs to be gone through and cleaned etc. I cant do it and there is no repair shops in Bend Oregon. I would like to find a new home for it and would like help on the value.
