Hello everybody, I have spent some time going through the threads but haven't found any reference to a good Sansui repair shop in Northern California. Does anyone on here have a suggestion? I have a Au 717 that has a channel out, and I think needs a pretty extensive recap and refresh. My local shop, which I have used successfully in the past, has totally failed me. They've kept the amp for 4 months now and finally let me know that they don't know what to do. It's obviously frustrating, but now I see it as a chance to have the amp well and properly refreshed. I love this damn thing and want to keep going for many years. Any help you could provide would be much appreciated. Over the years the AK community has been very helpful. Thanks!
