Mojotone's Andy Johnson provides in-depth information on the Mojotone's Blackface Deluxe Reverb Style Amp Kit build. Here he is explaining the transformer wiring of the Blackface Deluxe Reverb, 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.
