Topband: 8877 Tube

[Chortek, Robert L]

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.
