310 vdc on the plates... is that as measured to ground or from the plates to the cathodes?
Makes a difference.
With lower B+ I'd expect your amp to be very slightly overbiased and running a little bit cold if you are using a 250-270 ohm cathode resistor.
A bit more headromm can be achieved at a tonal cost, that being the "tweed Deluxe tone thing".
One of which is reducing some of the bass response and limiting the signal going into the driver triode a bit.
Give up some more voltage data and I can help out a little more.
