Check out the photos of the tube amp. It looks to be an integrated mono amplifier. I could find out muc about it on Google. It has a large cool factor, just wondering if this is something that's worth about $150? I sure wish there were two! Any experience with the reliability or the sound from this thing? It's a Knight KM-15. I assume the 15 is for 15 watts. It has a nice tube lineup and the condition is excellent. What's your take? See pics!
