Thanks for this "hard to find" service manual.
I apreciate the good quality of scanning and the pages scanned in A3 format.

Helpd me mont a new carradio when prewius mont was a mess.

Very good service and quick service, very good quality of service manual!

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 !
