Found the perfect housing for the RobRob simple bucking transformer, if anyone is planning to build one. The Hammond 1590KBK, all aluminum, very robust, just the right amount of space for a compact layout.

Need to dremel out an opening for the plug and drill a few holes, but drills fine with regular woodworking bits.

Do you have a link to the treatise on what that does, how it works and how to build it?
Thanks,
Gene

Nobody's yet commented on how OP omitted the switch. Nice and clean. If you need full wall voltage, just plug the amp into the wall. I'll copy that.

BTW, another transformer that can be used for this is a Triad, model VPS12-6300. It will fit in the same 1550K box that @Jason McG used.

Nice. That does look pro.

The aluminum lid looks nicer than a household switch plate, too, even the enameled metal one I finally found. How did you cut the hole in the lid for the outlet? All Dremel all the time?

And I may have missed it in the pics, but how / where did you anchor the household power ground?

yes, dremel and cut off wheel for cutting through lid, tidy up with a flat file

household ground to the ground terminal, with a lug down to the chassis, then from the ground terminal to the ground on the receptacle

Thanks for the extra build details. I’m thinking your build is a great, even inspiring, invitation to anyone looking to build one of these super-useful little guys….
