Excellent!! Got what I need and very fast!! Thank You

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!
