I just finished building my tube amp kit that I got from S5 Electronics. It's their 16LS tube amp that comes out at 15wpc and they claim is 4 or 8 ohm capable. (I'm running my Monitor 5jrs so split the difference) It runs eight output tubes and two input tubes. The amp is for my computer rig, so the fact that it is integrated is really nice. Soldering everything to the board was the easy part, but making my own wooden case and all the physical wiring and moving of components took a long time! However, I finished it last night, hooked it up, and boy does it sing. This is an amazing sounding amp and I am very impressed. Everything about it is good; from the warm sound, to the dynamics, and even the detail. It came out way better than I expected, and all for just over $200. There is no way that I could have purchased a comparable amp for even three times the amount I built this for. I'll post pictures when I get a chance today or tomorrow. Question or comments are definitely welcome.
