Perhaps Gordon or Trev can comment on the lower volume issue.

Notice that the plate voltage on pin six V1 is 110VDC. Perhaps a resistor to ground of, say 150K would bring up the volume without producing the distortion caused by the 270K resistor on the plate at pin 1. I assume also another .047 cap would be needed.
