Hi guys,
Hope you guys can share some of your experience with EL86 / 6CW5.
All EL86/6CW5 datasheet specifies Pa of 12W except RCA 6CW5 datasheet where it mentions that class A1 permits Pa of 14W. See below:

All the others specify operating point of Pa >12W or at 100% of Pa, like follow from Mullard EL86 datasheet:
- Pentode Va 200V, Ia 64mA; Va 170V, Ia 70mA
- Triode Va 170, Ia 74mA
So, should the Pa be 14W for class A1 or it should be 12W?
Has anyone run EL86 / 6CW5 at datasheet recommended points and it is working fine and ran for thousands of hours?
Thanks!
Ken
