At low power, I suggest u go for 845 more than 211. You can have 15W, 750V plate, -98V grid, 95mA plate current, with 3.4k ohm output transformer. So, your can have a 30W+ output transformer either for 300B or 845.
I remember someone here said operate 845 at around 500V. Someone also told operate 211 at 560V and 10k output for 2W output. Anyone can tell me the operating point?
