There was an article published (Handbook? QST? QEX?) for homebrewing a 2m
kilowatt-class amp using the 3CX1200Z7/YU-181. I'm wondering how close the
Henry design is to that.
The Z7 is a nice tube for HF and low VHF, damned near impossible to kill.
Too bad they've gotten to be so pricey. I found one company that says they
will rebuild them (can't think of who it is off the top of my head), but
haven't tried them.
