At this point I feel a little stupid saying that a nice stiff rectifier can help with the speed issues. I've had not trouble doing better than the Sovtek for rectifiers; even the old winged C Svetlana is better. I've had the best luck overall with the later US military versions, which in this case would be the 5U4WG, I think. I remember thinking at first that they lacked subtlty, but it turns out that they do not; they just have notably more guts, and as a bonus they are cheaper than some of the exotic stuff.
Looking at the circuit, I can see why you settled on it as a starting point. But we might even say, the simpler the circuit, the more important the parts.
Maybe use the driver halves parallel?
