Portable Reel to Reel player

I don't know too much about this unit

I did try putting batteries inside but nothing happened

You might be able to rung this from an AC adapter but I've never seen 

a power cord with that prong set-up

Looks like there is an old paper label down inside the hole in the front 

(right above the TK1) I though it was dust but it's not

This is a heavy little unit weighing 11.6 lbs

Will be shipped with care from USA
