A large number of square stamped pans nearly perfect in size to build a
monoblock tube amplifier are being turned out by one of the large burger
chains as they change their equipment out. They are stainless steel and of
pretty good thickness. Restaurant supply outfits have them for a couple
dollars apiece. My source won't say which chain but I suspect Wendy's.

They have a raised rolled lip that will take a cover by sliding on, and
the sides have a nice rebate that will make a good front and rear panel in
either orientation.

I've had great success with the rectangular sterilizer trays used by
a lot of VA hospitals. They have a sliding cover that locks and a
bottom that is heavy gauge perf, like old microwave oven door screens.
They are a nonmagnetic stainless steel or some alloy like K-Monel.
Unfortunately unless they're completely trashed, they aren't surplus-
they're stolen. I found that out after building several S-Line power
supplies on them. They're well over $100 new apiece and they last 40+
years.

I liked your suggestion of automatic transmission oil pans until I
went to look for some. Most are too small or have a weird shape.
