is this pentode sensitive to changes? Maybe an update to a higher AC line voltage remedy. What was the original spec...115vac? Then 117, 120, 122...it's been climbing ever since but mostly years ago when it was in production.
I can think of no other reason because the drop is more than 6%. Question is - why only that tube? I'd like to read the answer to this.
BTW my AC line varies from 127 to 114 throughout the day/night according to demand and the sucky local PSE&G in NJ. My Panamax tames it.
Follow Ups:
There must have been a reason other than line voltage, but darned if I know what it could be.

Maybe the designer just like the parameters of the "new" tube that was created by running the heater at a lower voltage?
