Mojotone's Andy Johnson provides in-depth information on the 5E3 Tweed Deluxe Style Amp Kit build. Here he is prepping the chassis (mechanical assembly), and discusses some common things to look out for, as well as the 'hows' and 'whys,' surrounding this portion of a kit build. This is a good resource for builders and techs of all skill levels, as many of these principles can apply to amp kit builds in general.
