I had to model the first stage of that circuit to be sure what was happening. It appears to be a follower, not a CCS as I first supposed. Nearly all the output signal current is supplied by the MOSFETs. Seems pointless to have a tube in the circuit at all. Why not just build a MOSFET amplifier and save the cost and trouble of a HV supply? Definitely not something I would ever do... :)
