this is a used preowned radio shack tandy MMS-10 sound system.it was tested and does seem to work as intended however to be honest there is some staticy if you will in the switche when you turn the knobs.there is wear on this machine.there are scuffs,scratches,nicks and dings on the unit.on the top in particular but elsewhere as well.black marks are apparent.there is a dent on the left hand speaker,top left corner.yellowing and discoloration of the case is evident on all sides.edge wear is also apparent.the feet if you will on the bottom of the system has the same wear,scuffs,scratches,etc. in short a used preowned sound system with some cosmetic and some sound defects.thank you for looking at this listing.
