After many, many amps of every possible flavor, the sound that sticks with me is a great 18w Marshall. I'm thinking about getting an SDGvintage 1974x kit. While I have 3 yrs of MILSPEC soldering in my background, that was long ago and my chops are at about 40%-50% of where they were. (I expect they'll come back pretty quickly, though.) I'm reasonably confident I can work from the layout diagram and a couple of hi-res gut shots, but there are no instructions and no forum at the SDGvintage site. So! Anybody built one of these SDGvintage kits, or successfully built an an 18w in general? If so, how much experience did you have, and what sticking points (if any) did you have?
