At first glance that appears a little on the high side but on further consideration that seems about right. An 813 has about twice the power dissipation of a pair of 811s. The Tiny Tim using a pair of 811s can run 300 watts output on CW with 100 watts input. That is 300 watts continuous or 600 watts pep. I think the ZL1AXB design is not only neat but exceptional.
