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 !

I am a vintage hifi collector. No way to fix that device without the appropriate service manual...thanks to your site I got it and every thing is easier now. I got the manual right after ordering: fast cheap accurate ... thank you

Wonderful job clear. Qick fantastic. These people are really good. If even a problem arise they are wonderful assisting you. These scheme is so net despite this is a very old TV. Thank you for everything!!!!!!!!

Detailed schematic diagram, manual for professionals

Good service manual,exploded view,adjusment and test point locations,head alignment,mechanical checks and adjusments,all perfect.
