If you have had the fan whine problem, and had it fixed. Please tell what you did. My receiver finally started to develope the whine problem after a couple of years of use. I would like to fix it at home, with out having to ship it out, as I live in an isolated location. But, if I have to send it I will. I do have an auxilary fan that I set on top of the unit when I am playing it loud, but it is quite noisy and unacceptable at low volumes. Any help on how to cure this problem will be greatly appreciated.
