I extended the NPN current sink by adding an additional transistor at the emitter of the MJE340. This transistor was driven by a pulse, about 100 Hz, making the current through the tube be pulsed. This is required for using IN-9 tubes, otherwise they will not operate correctly: sometimes the glow will start in the middle, or maybe the glow will extend from the top-down. The IN-13's tried to fix this by adding an auxilliary cathode pin, but I'm not sure how well that works.
