Ok, so this is the second time this has happened now. I just got a new rig that consists of an Acme Low B-4 Series II, a Stewart 1.6, and a Dememter VTBP-201s. The power is supplied but some cheap Furman power conditioner. So, my rig will last a couple of hours bridged no problem. But eventually I think it starts to run out of power. As far as I know, the Stewart continously draws power from the conditioner instead of charging up, so to speak. It doesn't really create a reserve. So, when I start really digging in, like slapping or something, one or both of the channels will turn off. When I try to run the cab with only one channel, it'll last longer, but any heavy playing will cause it to turn off again. My guess is that the power conditioner isnt allowing the amp to draw enough power over such a long span of time. Has anyone had this problem? Should I get another power conditioner or similar device? Any help here is greatly appreciated!!! It really sucks when I have to drop out of the mix because I have no power. Ask me any question you can think of that may help you understand this problem and help me work it out. Thanks a bunch in advance everyone!
