Build the Bartola Gen 2 01A preamp. You will get much better results. You will need a pair of Rod Coleman filament regs, to be used in filament bias. See Lyrima.com. And a couple of Gyrator kits from Ale Moglia, see Bartola Valves.

I've built loads of 26, 4P1L and 01A line stages with all kinds of configurations, and the Gen 2 is the best - by common consent - of all these builds.
