Vintage Roberts Model 770X Tape Recorder Reel To Reel Player Not Tested. Condition is "Used". Shipped with USPS Parcel Select Ground.

The unit turns on.  When I switch it from slow to high speed I can hear the speakers make a noise.  I just dont have the tape to test it with but I am pretty darn sure it works.  Was purchased at an estate sale that thr guy had a few of these units.  Over all great condition.  Please look at picks.  I cant get the forward and reverse knob to turn but maybe it requires a tape installed to do that?
