see you upped the bias to 4V and the driver is giving you a gain of 12.8. This puts you at just over 50Vrms (70V peak) into the grid of a tube biased at 50V so everything looks to be in line and I don't think you will get much more out of this situation. (unbypassed 2A3 inot quad esl63's)
This doesn't explain why a preamp that puts out an alleged 17V needs to be turned up all the way since that should cause some pretty severe clipping to an input stage biased at 4V with a gain of 13
