That 17173 looks to swing about 0/50-50/0mA. So you could instead put an EXO-173 before the driver (at 750Vp, the date sheet requests just that EXO-173's 150vrms swing, from grid to grid), and put separate chokes on the cathodes, with low DCR to keep the 811A grid bias near zero. That 811A is pretty versatile, the last triode hurrah... --keto
