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. |
