That 10Hy choke is between the B+ supply and the driver tube, not between the opt and the driver tube even though that's how it looks. The B+ supply is feeding both.
You could use a resistor in it's place but you would have more PS ripple on the plate of the driver cathode follower stage and the plate of the voltage amplifier stage.
