One more thing, here's my idea for a very cool little amp:
New head style cabinet for the amp. Make it as small as you can but wide enough to match the speaker cab. There's a vent in the bottom of the chassis, so cut an opening in the bottom of the cabinet for it. The feet will keep it far enough off the speaker cab for air flow.
The bottom would be a 2-10 or 2-12 slant cabinet, built like a 1/2 of a Marshall slant cab. Think of it as a quarter stack. Partially closed back, but not all the way so it's not too directional or bassy. speaker would be 16 ohm in parallel.
Use some nice mahogany dimensional lumber, dovetailed joints, finished in a natural oil. No corners, just a handle and feet. Route the outside edges with a 5/8" or 3/4" roundover bit. Wheat colored grill cloth.
I think I just wet myself....
