Other than the unfortunate quadrupling of heater current....

Vacuum-tube digital computer.
Oh, sure, you need some twin-triodes too. But early computers (vacuum, germanium, silicon, and even DTL and TTL chips) use diode-logic as much as possible.
It's been a while since I ran optimizations like this. I'm gonna speculate that "hundreds" of dual-diodes could build an 8-bit full adder. Two sets of 8 toggle switches, one set of neon-lamp outputs, and you can add any two numbers from 0 to 255 as fast as you can work the switches.
If you lived in the land of 120V: put about 20 heaters in series, all 40 plates in parallel, you could build a death-trap trickle-charger to keep your lawn-tractor battery topped-off all winter. "Death-trap" because you have a 50:50 chance of having 120VAC on the battery terminals. This is bad enough, I don't think you should consider 40 bottles for a 240V battery trickler.
> VTVMs. Every one I've ever seen has a 6AL5 in it.
Yeah, but I've never seen one fail? Unless you blow it by probing your 211 amp plate, the total ampere-hours is about zero per decade.

(The 1N4148 of the tube world) other than BB gun target practise.

I'll take a few. I'll paypal you some cash if you are interested.
