Estate Item. Purchased in Japan. One Owner. . Sprayed all switches and pots with Blue Works contact cleaner and powered it up. Nice audio. I function tested the unit through the aux and tuner inputs. Works beautifully. This is a Vintage piece of equipment and sold for parts or repair. You tube video below taken with my phone. Sorry the audio recording is not so hot ( droid phone.) Cosmetically nice for it's age with a few scuffs and scratches. Smells slightly smoky. Might need to blow it out and air it out. I'll leave cleaning to you.It's been in storage for a few years.
