I was thinking somewhere in the neighborhood of 750 watts.
The AL-1500 would run approximately 400 watts AM, comfortably, roundtable
style, last time I saw one. Keep in mind, this is 2-5 minutes on, then an
interminable amount of off time.
That's 1600 PEP, unprocessed, which just about jives with what Ameritron
states, averaged over time.

It's a sad state of affairs when your tubes don't have handles but your
dummy load does.
