I agree with Jeff: a direct coupled 6K5 to 71 would be the cat's ass. I used a K&K CCS on a 6K5/2A3 amp with the compact cascode CCS set for 1.3mA. Ask Kevin for a 5k ohm pot to replace R2, the 1k. Note the 6K5 will not drive the grid of the 2A3 to 0V as the 2A3 starts to draw grid current about -5V; the 71 may be easier to drive. BTW: on the drawing Channel 2 should be 510V.
