The problem with cardboard in close quarters with vacuum tube equipment is the heat. The multi-section cap in my Dynaco ST35 is less than two inches from the output tubes, which run at 240F +/-. For just one example. Not that there is any danger of fire - but it is quite warm. I also want the metal can look. I have found sources, even at reasonable costs - at quantities of 500 or more.

ah, I misunderstood. I have seen a LOT of multi-capacitor cardboard
types but you're talking about a metal can. Yeah, maybe you can get
some blind-end aluminium tubes, or aluminum tubes with end caps, to do
the same job... ok not *exactly* the same but still. You'll still need
some kind of insulator for the terminals. Maybe you can get some
circuit boards made to do the job? Would need a lot of precise metal
cutting for tabs, etc. on the aluminum. yeah, starting to sound like
too much effort already...

But inside the capacitor can I'd hide some "modern" electrolytics which
are considerably smaller in size. I've heard of this being done in
radio restorations where they dig the contents out of the can, swap in
modern components, but give it "the look" of the original system.
