A 3 tube sb220 that makes 4900 watts??
Okay, I know that in the beginning of this video I kind of made fun of this amplifier because I thought it was incredibly unsafe, as I started working on this little thing I had no choice but to admire the brilliant / Innovative / creative / redneck engineering that was in this thing. At the end of the day this amplifier really got with it and I mean that on a serious note. Not going to lie by the time I was said and done I was very happy to have the opportunity to work on this and I learned quite a bit from it. Please enjoy the video. This took three straight days to make for you guys..
