Bobolon1 introduced me recently to an interesting tube: The GU50. Availible for under $10 on eBay, a push-pull amplifier is capable of 100 watts or more, and it has an output impeadance of only 2k.
If two of these tubes were used to create a Circlotron-style amplifier, the net output impeadance would only be 512 ohms. And this can be dropped by wiring in parallel.

So, what do we do with this?
Arrays!
By using 8 32 ohms guitar drivers in an array (or 32 8-ohm drivers - yikes!) a net impeadance of 256 ohms can be produced.
Assuming that an inexpensive power supply (solid state seems to be the only way to go here!) can be found, the end result might be a very powerful, inexpensive amplifier that would sound different from anything else.
Any thoughts?
NOTE: I'm aware of the high-voltage issue.
