The transformer & IEC socket holes were cut with a Unibit step drill bit to make the corners and a Dremel tool to cut between the corner holes, the tube socket holes and the rest were all cut with a Unibit. The terminal strips are laid out so the preamp section faces between the input jack and pots and V1, the filter caps face the power and rectifier tubes. Pardon the grey plastic covering on the exterior of the chassis, that will go away as I get a little farther along. Next up: mating the chassis with the cabinet and acquiring the last few components for this build.
