So I was told at estate by the daughter that this has always just been in the box as her dad never ended up using it. Looks brand new. I quickly set up on a modern amp but I don't think I have the right connections..basic functions all work but using an aux input on my receiver and both sets of outputs on the Hitachi-- it sounded muffled but it's definitely playing well and switching tracks etc.

From what I can find these are very rare and if it does end up needing work it is definitely worth restoring based on condition alone. Includes original box as shown
