Selling this as-is/parts-repair, no returns. It has worked intermittently. One time I turn it on it works, next time I turn it on nothing happens. Not sure what’s up with it, but it will need some fixin’. All the lights seem to be good, cosmetically it looks great, very clean. Very nice unit. I have the matching C-80 Natural Sound Stereo Control Amplifier and will be posting it soon in a separate listing, in testing it has performed flawlessly.
