Unitrol 80K amplifier. I don't know anything about it. A tenant left it when he moved out. It looks like it's in good condition. The fuse is not blown. The pictures will have to answer all questions that you may have. When you are ready to walk out the door and pick it up text me and I will give you the address. Not before. You can text me at ate 057 won 0 3617. Text only please. No emails or phone calls. Thank you for recycling.
