[Amps] figuring tube output impedance

[Partain, Chuck]

I'm looking at the drive not being ON FULL and low watts in, hey it'll coast at 1500 if I do all this right
which is what I was shooting for in the first place, that alpha key down advertisement long ago got me thinking.
I have also email here from a year ago about me deciding what I needed for a gu-84b tube and lots of folks wrote back saying 3.5-4 was a "good working voltage" for this tube. there just wasn't enough info on it and I HAD ONE INEXPENSIVELY! Plate voltage is no issue as I am the sales rep for magcap but its work I didn't want to do at this point.
 
will see what shakes out, I also have a cantenna I built oil filled and I have the mfj 1500w tuner with a dummy load in  it, I don't intend on seeing "what the thing will do" boiling off oil and making flames!!!
 
I did however get questions answered on the ORIGINAL question I had asked. thanks for your inputs. I'm going along the correct track as I thought.

With 3900 watts you can fry tasty chicken in the dummy load if you use
vegetable oil. Think the FCC would fall for that one???
... I actually had a dummy load filled with vegetable oil. Worked ok but oil
gummed up around the heated metal contact points after a while.

yea they're going to love me.

and I guess with that line of thinking, I should drive home doing 145 in the
40.

I'm GUESSING the FCC will be very interested in your amp.

Even at a lousy 50% efficiency that is 3900 watts output.
