Schedule 40 electrical box from Lowes 6" x 6" x 4" tall

Notes:
If using the schedule 40 PVC box you will have to run a ground wire to one of the mounting screws on the pre-amp tube socket so that it is grounded and the shield will work. You should also vent the box with a hole or two to let the internal heat escape. Remember, it's a PVC case and so nothing is grounded, you have to ground everything manually. The thicker PVC case also means you will have to use the L12A switchcraft jacks.
If using a champ chassis and an EL84, you will have to make a plate to reduce the 8 pin power tube hole down to a 9 pin hole.
This is not a kit, you must have enough skills to figure this all out and be able to do it properly. No support is offered by Hoffman Amplifiers on this project.
