I had the repair done by Henry Koch, htkclk@juno.com. When I initially contacted him, he indicated he was quite busy but gave me a window when he would have more time. I contacted him again around that time and it took about 8 weeks door-to-door for the repair and cost about $130 including all shipping charges, parts, and labor. He also included a 90 day warranty on the repair, though he gave it a burn in to make sure all was in order before shipping it to me. He provided a specific detail of the repair but I prefer not to provide all of those details. He did me a service and is trying to make a little money. Here is a summary of the work. He replaced 29 components, adjusted the subwoofer amplifier current, and installed a fan and its power supply.
As others have said on this board, my comments are my opinion. I don't know Henry and don't have any recommendation one way or the other. I will simply say that I am satisfied with the services he provided and the communication we had. Your results may vary.
