This is an awesome amp. Not the prettiest thing in the world, but it sounds fantastic. It's the original 3B. No ST or SST or anything else. I had mike go through it and replace bad caps and upgrade the big filter? caps about a year ago. I have an extra power button for it (thought there was an issue so I ordered a new one). There are some scratches on the amp, but functionally it's 110%.
