Tube regulator for removing ripple . . .

I'm currently building a 4kV DC supply for my VTTC which will be used for a
high-quality plasma speaker.  The only problem is removing the ripple on the
output of my full-wave rectifier to the point where the DC is very clean
(<10V ripple) Sure, this can be done with a boatload of capacitance but i'd
rather go about it with some type of floating linear-type tube regulator.
With 10-20uF capacitance I basically still have about 50-100V ripple
depending on load.  I used both solid state and tube regulators for doing
this same thing on a very large scale but never on a small scale such as
this.  Solid state would be nice but it is quite complex to get working
correctly and relatively expensive.  On the otherhand, maybe a simple tube
driven regulator my be a simple, inexpensive alternative.

Any one have experience with this and know of some small power tubes that
can do this???

Thanks
