<div>I had one of these and they were good low band recorders.
This one has an editor in it. The alignment tape would be
nice to have. This machine was used for winding tapes because it
was not high band. It also served as a spare parts bin for the
TR-60 we had. Control modules, and servo amps were the same.
And you get the book. <br><br>Chris Hill</div>
