There are about 7 places to send your amp and this is without the input from worldwide locations. So if you want us to recommend a place, it would be better for you to fill in your location in your profile and it will appear under your avatar and folks could say something like, "Oh, he is in Northridge, CA, best place around those parts is Northridge Electronics, Simi Valley, CA, where Tom does excellent work." Or you could sent it to Scott in VT. We don't know what to recommend.
