Tube watts & volts

I'm a little confused on two areas,

Is the voltage rating of a tube, say, 1500 for an 811-A, peak or rms?

The other question I have is the wattage an 811-A can handle. In the back
of Brent Turner's book, it is listed as having a plate wattage capability
of 65 watts, but I've seen circuits, specifically two push-pull
oscillators and a driver for a sonic bath, that use them at over 200
watts apiece. ???  I'd be glad for a little help here, since I KNOW there
is someone with the answer out there...
