Default Tubed voltage regulator for KT88se amp, need help ?

Hello,
Last year I built this amp:

stereo SE kt88 build ... abdellah diyaudioprojects design

It has been one of my favorites. I have all the parts to build another one but this time I would like to add a regulated (tube) power supply. I have never used regulated supplies on any of my previous builds but have heard praises sang about the benefits of regulated supplies.

I was hoping someone might have a fairly simple, easy to construct design that I could implement in place of the unregulated supply for this design.

I want to use all tubes as I have a lot of real-estate on my chassis.

Thanks for your help in advance.
Jeff

steve bench's series of articles on tubed regulators, although you've probably been there already...

Ok,
Thanks for the great links. I have read all the info there, I think I have a good understanding of how these different topologies work. Problem is I don't think I am savvy enough to create my own design "de novo". What I am really asking for is a "drop in" regulator circuit/schematic with all the component values figured out for the amp at hand.
Second best would be a schematic close enough that has adjustable features I could "dial in" the proper voltage. Can anyone supply me with a schematic I could use like this on this amp? I already have an identical amp built without the regulated supply. I could build the circuit on a proto board and splice it into my existing amp for test and tweak purposes. Once refined I could build another amp with this circuit installed.
Jeff
