Man, this is so awesome! I'm totally psyched that this forum was started. I'm a total beginner when it comes to these amplifier projects but I'm starting one right now. Mine will not be in the same league as any of yours but I'm just really happy to have a forum here on HTS. I've tried following threads on DIYaudio.com but they are way too advanced for me. I will start a thread in the next week or so. Hopefully I'll be able to get a lot of helpful feedback.
BTW, not to be a grammar or word jerk but, judging by the care you put into your projects, I thought you'd want to know the correct engineering term to describe what you mean is "damping". "Dampening tape" would mean that it, like, gets something wet. Sorry, it's a little pet peeve of mine. In my previous job I designed damping treatments for spacecraft systems so that they could survive launch. In that case, when a payload got wet it was usually a very, very bad thing :R
