N-set, I am sure you realize by now that I do not properly understand "electronics".  I see the "diodes" in the Chimera circuit as a sort of "active" bias that is also dynamic proof against blowback/ripple to and from the tank, at each of three "levels".  I don't have the circuit where I can look at it now, and I don't really remember it all thet well, but I thought I remembered it was meant to be a "constant current" design, with the final diode (output) as "insurance"?  I guess the corrected curve would "replace" the middle gain stage?  I also think I remember that the designers considered the "speed"/rise/discharge time of the ground-plane caps to be very important.  Likewise, I think the "diodes" are not just any old diodes.  Naturally, I don't know how this circuit translates from ~7W to ~150W.

Best regards,
Paul S
