Very Rare Vinatge DENON pma-830 solid state amplifier. These were built in the late 1970s and are absolute tanks. The sound quality is amazing as you can research and find these were beauty amps. 65w/ch rms. It works very well just no room anymore for it. There is some dust on a few of the switches amd pots that could be cleaned out fairly easily I would think. Check these out. Only 1 other unit on ebay I could find.
