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!

I'm quite impressed. I had to wait 24 hours for my manual (quite a rare one) but I got it and the quality was good. Also, from trawling the web, these prices are by far the best.
