I have one of the Stewart PA-1000 amps, one of the single space lightweight units. While I had read about the shutdown problems, I had never had a problem until this weekends gig. I run the amp bridged, on an 8 ohm load with my 410xlt. EQ set flat, gain set as reccomended, limited engaged with a slight bit of compression to even out the spikes on it, it died on me for about 30 seconds or so right in the middle of a song. The amp was not hot at all, I leave two spaces above, and one below open in my rack, and it was about 60 degrees out saturday night when it happend. I was pushing the amp pretty hard to keep up (75%, cab was farting a little) due to being an outdoor gig. I did although figure with the touch of compression, limited engaged on the pre, and the light 8 ohm load, I would be okay. Is there any way to prevent this? Sometimes you HAVE to push it a little more than you like in order to be heard. Also, the amp is 700w @ 8 ohms bridged.
