I do agree,
At present I am in the process of refurbishing a russian military autotune
amp 1,5-26MHz with GU78b.
I just started with cleaning, but I already ha a look at the output network
and that contains two pancake coils as you described with a static shield in
between. So it must have worked like that in the past as well.
The coils are exactly the same and wound of 4x6mm square copper wire.

I do a lot more calculating than I do building, so I don't know if this
coefficient of coupling figure is practically attainable or not. I'm
starting to
think that it is because it seems like you could couple a lot more magnetic
flux
lines with two pancake coils face-to-face than you could with two solenoid
coils. You builders out there, do you agree? Disagree?
