I started off with a marshall 1974x 18watter amp , then did some of the metro plexi's , etc. I recommend checking out trinity amps out of Canada. Their amps are top notch and they have great instructions and a forum for help if needed. The parts used and chassis are really nice and their prices are fantastic. They offer mostly small to mid watt amps in each category. Marshall type, vox/matchless type, hiwatt type, fender tweed type. I plan on doing their Hiwatt inspired amp called the triwatt which looks like a fun build. It sucks that ceriatone no longer offers kits but they never did offer the afd or chupa in kit form anyway.
