Illuminati (2nd Degree)

Forgot to add - check for oscillations, I have a problem with all those high-gm tubes. Use g1 stopper, g2 stopper (g2 to anode), and use both cathode connections - I use two resistors, but one Rk+wire bypass to other cathode pin worked, too. Where you connected g3?
Somehow I can`t believe that you and I get totally opposite results?!
