45 tube B+ question...HELP!

I am experimenting with a 45 SET amplifier circuit as follows:
6SN7 driver with interstage transformer secondary to the grid of the 45, 1.35K bias resistor and 25MFD oil capacitor in parallel to it from the cathode to ground...the filiment connected to the typical hum pot arrangement. The plate is connected to a 3.5K Single ended output transformer. The question is that I have 310 to 320 VDC measured at the plate of the 45 to ground. The amplifier plays fine. Is the B+ too high to be safe for this tube? I notice no "red plate" glow and there is no distortion. Thanks for your input.
