Default Low voltage 6922 preamp...wanting a schematic

Hello,
I was sifting through my stash of parts today and came across a few 30VCT transformers and some 6922 tubes. I have all the parts on hand to build a low polate voltage linestage it appears but, no schematic. I recall seeing a schematic somewhere that uses a 6922 in a simple CF orientation with a plate voltage of around 30v. Does anybody have this or a similar schematic? Even a SRPP would be acceptable. I have no end result in mind oither than using up some parts for a weekend project. Any help greatly appreciated.
Thanks,
Jeff

Then I seriously suggest you series up a couple of those transformers and get some decent voltage for your tubes. At 30V B+, it will be very distorted, with 90V it could be a thing of beauty.
