Count me in the "don’t overlook your driver tube" camp.
300Bs (and directly heated triodes in general) are very responsive to the driver, and what worked with your JJs may be the wrong driver for the TJs (or other higher resolution 300Bs).
Just because they’re Mullards, doesn’t give them a free pass for all applications.
