I would think these RF input versus RF output numbers are reasonable. Everyone's setup will vary for all bands.
I haven't looked at the KPA-1500 Utility in a while, but "real" efficiency of the amplifier is a different calculation. Amp efficiency is Power Input versus Power Output, and per Elecraft that is somewhere around 50% or so. If you had the equipment to measurement the power input, it would be somewhere in the 3000W range I would assume with a 1500W output. That is why the fans are required and the ventilation of the unit is critical, as there is a lot of heat being dissipated to the space as was discussed in other posts.
