This is a 5E5-A Tweed Pro build in a 5F6-A Bassman Chassis(room for growth!)and Head Cab. It includes a bias pot, external bias test points, and the impedance selector switch for use with 2/4/8 ohm output transformer. Components on this one are Weber VST and IC Electrolytics, Sprague Orange Drops, Weber VST & AB Carbon Comp resistors, Weber VST Chassis & power transformer, Mojotone 2/4/8 ohm output transformer. As with all of my builds all wiring is ABOVE the board to accomodate modification or repair without having to remove the board. Here are some pictures of the build process.
