Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !
