I actually picked up a couple of those chassis from Welborne on a clearance one time...always wondered how to figure out the placement of the items 'under the hood'...think I might add a "BB proof half monkey ala DRD chassoise" to my hot stove on deck circle...

If you go to their website (still in business I guess) you can buy a PDF of the construction manual. I did it weekend but it didn't open, but a day later they sent me an email copy. Anyway, clearly Paul's circuit is different / better, but this is a great guild to the layout.
re: "...clearly Paul's circuit is different / better", mine is nearly identical in conception - I bypass the 2A3 cathode resistor instead of the driver cathode resistor; that's about it. The topology is so simple, there are few variants possible.
Mostly what I have tried to offer here is some specific parts values as a help in getting started, and a description of how they were chosen for those who want to make modifications. Plus of course I could not have put someone else's commercial design in the public domain!
