This is an early 1960's SONY TAPECORDER Model TC-105 Reel to Reel tape recorder and player.  It has a built-in amplifier and speaker or IT can be used as a deck only with an external amp and speaker.  Unit measures 14" by 13" by 7".   It weighs just over 20 pounds. Excellent original condition with little wear.  The Microphone looks unused and fits into a compartment on back of machine with the power cord. Note that is a MONO, not a Stereo unit.  It appears to be working and is sold on that basis.  A piece of consumer electronics history.  Guaranteed to please the new owner or I'll buy it back.  Check my Feedback.
