If you're building a power amplifier the load impedance has to be lower than in a voltage amplifier, otherwise no work would be done (the amp wouldn't have much power).Again, the 6as7 is not a very linear tube. It will not give much useful power no matter how you load it unless you're willing to accept a high amount of harmonic distortion.
Pete is saying that it will give some useful voltage (at a low output impedance with plenty of current capability) for use as a preamp but only if you load it into a really high impedance.
