 ;
Manual acquired with good resolution, complete in all its pages, very good policy of the folder where are saved all products purchased.
 ;
Service manual very complete and clear. It was very helpfull for my work.
;
This is the 2nd time I download manuals from this website and I can say it's what I was expecting. It contains schematic, layout (decent quality), short description, parts and dissasembly instructions. I recomend it for anyone who wants to repair/modify this device.
;
Very useful Service Manual! With it I was able to identify the damaged pots in my old amplifier, purchase the adequate replacements and make myself the repair.
I have again my old amplifier, still a very good one that I will keep for as many years as I can!
Thanks to Owner Manuals!

Good price for the manual and easy to locate on the site and download. Plus, just like the original. Thanks a lot.
