For most circuits this should be well within the tolerances of the design, but you can ask the manufacturer to be sure.
They all sound best with a good deal of current running trough them. On my schematic the hand written voltage looks like maybe Silicon suck at this: Anonymous February 1, at 2: But the 12BH7 is a tough little bastard.
