This is in very good cosmetic condition. There are a few scrapes here and there. 

I tested this briefly by hooking my iPhone directly and it amplifies music cleanly. Both the left and right volume pots raise and lower the volume level but with a bit of static. I did not test any other controls. 

This is an amazingly well built unit that, in my opinion, is a big step above contemporary units from Pioneer and Sansui. It may even be slightly above what Kenwood was building before the exodus of Nakaichi and Jiro Kasuga (to found Accuphase). It weighs 30 pounds before packing. 

I sell all 50 year old electronics as "for parts or not working" regardless of how they perform. This is 50 or so years old and should undergo a thorough exam by a qualified technician with repairs and updates performed as needed. It is offered for sale in as-is, as-pictured condition for parts, repair or restoration.
