: hey my names shiben , i play bass in austin on a Sunn coliseum head the big one, i can't find any info on this bad mother of an amp, no one knows anything about it here, i would appreciate any info anyone has about it, or just talkin' shop.. later!
I used to have a couple of those. They are LOUD. There is some info WAY down the page in an interview with the Sunn founder. Those amps are bullet proof, and quite flexible. Neither of mine would develope the 320 watts @2ohms claimed, it was more like about 275, but still quite a bit. I also measured @4ohms and got about 180 watts. I always prefered the sound of my tube Sunns, but I used the big boy when the others ran out of gas.
