So, if anyone is interested in building an amp, the BYOC Champlifier kit was an awesome starting place. The step by step instructions make it incredibly easy to build, as long as you have soldering experience. Standard disclaimer: tube amps have lethal voltage, etc., etc. so don't build it unless you understand what you're doing. Seriously though, the kit was a very enjoyable experience. The instructions were top notch, and everything fired up on the first try. I was also surprised at how dead quiet it is, and it's also louder than I expected. It sounds freaking great though! I can't really let it rip in my apartment, but it sounds great even at low volumes. I opted to go with a 10" Alnico Jensen speaker though, and I'm incredibly happy. All that being said, amp porn!
