I think a 211 linestage is a great idea! Let's start with a 10k B7...and, of course, it's gotta use the Dowdy plate choke
:-)A quick glance at the plate curves leads me to believe that approx 420 vpk @ 40 mA oughta work well; G(v) would be about -18 v; which means a 470R cathode resistor [rated for at least 2 W] should be a good first guess...and, I saw some cool 70 mfd oil caps on eBay that would make for a very cool bypass cap!
Happy holidays to all.
