Bond is a real good guy, he also fixed a soundigital 8k for me, he only lives like 45 minutes away from me, from what I've seen, most stetsom blow from operator error,even my set-up, I can't blame the amp or the company if mine blows because they don't advise half ohm nominal...I know they get damaged a lot during shipping from brazil, both of mine where, if I had hooked them up without Bond correcting what was damaged in shipping, I'd be in the same boat as a lot of people that have these amps blow on start up. Another thing about the technology in stetsom, you have to let the caps charge, especially in the big amps with all those caps and high rail voltage. I have a remote switch that I can turn the amps on/off with. When I first turn on the radio, I leave the amps off for about 3 minutes to let the caps charge, hope this helps.
