Hi all, I've been using a Stewart 2.1 for a while now, it's a great lightweight amp that cranks out 2100 watts into 4 ohms. It weighs 17 pounds. That's a beautiful combination. I've heard some interesting things about the company though. First, I heard that they don't release schematics "period", not even to qualified service techs. To get a Stewart serviced, you "have to" return it to the factory. Is this true? Does anyone have any experience with Stewart's service? Are there any amp techs out there who've serviced Stewart amps? I'm especially interested in the switching power supply, it'd be nice to see a schematic 'cause I'm curious about what's in there. Are there any other lightweight "power" amps that use a switching power supply? Schematics anyone?
