Is that at full power out or in standby?

Subject: Topband: 8877 Tube
Wonder if someone can help with a technical question with the amp I use on
160 meters.
The Spec Sheet for the 8877 tube lists the "Absolute Maximum Plate Voltage
of 4000 Volts" for the tube, and also says in "typical operation" the
plate voltage is between 2700 and 3500 volts. In my amp (Ameritron
AL-1500), the plate voltage is 3750. My question is - should I be
concerned (it's clearly below the maximum" but above the range that is
considered "typical"? I just want to be sure I'm not adversely affecting
the useful life of the tube.
Any help would be appreciated.
73,
Bob/AA6VB
