Hello Devon.

I haven't any finished plan for you, but I tought about building such a 
thing, too.
However, I did not find the time / motivation to finally build it, but 
maybe I can
help
you with some thoughts.
Of course you could use a regular, of the shelf, power converter, this 
would probably
the
fastest way to get usable amounts of 110 / 240V AC. But then you have to 
worry about
any RF frying the power converter. If you manage it to filter RF good 
enough to let
the
converter survive, your device is probably "clean" enough to get your CSA 
approval
;-)

This led me to another idea. I know the military uses, or at least used, 
devices
called
"dynamotor", to power vacuum tube based equipment in their trucks.
These are combined 24V DC motors connected to 220V ( or similar ) AC 
generators.
Maybe you could get one surplus or you could even build one yourself.
All you need is a strong dc motor, which should not be a too big problem, a 
small
generator, some way to connect both and some simple device to gouvern the speed
of the DC motor to get close to 60Hz on the AC side.
One might use the regulators that big electric model boats or cars use to 
vary the
speed.
Such a dynamotor sould survive pretty good in the harsh environment of a TC.
What power-level do you intend to build, depends a lot on this if this idea is
practical.

best regards

Christoph
