Same here!  The 6907 is the next step above the 832A
and below the 829B.  The 5894 is the next step above
the 829B and the 8643 is the next one over the 5894.

There is no way a 6907 is going to put out 80 watts
and last very long in a practical circuit!  Motorola
used them in some of the 15 - 18 watt output mobiles.
I have several around left over from when I owned the
Motorola reconditioned equipment center for the
south-central United States.

They are about 40% of the height of the 5894, about
the size of the 832A except they are pretty much a
cylinder in shape.  They are a pretty good VHF / UHF
tube, at least up through the 70 cm band.

In my experience with the 6907's (I have a few here
somewhere) the  maximum I ever got out one was about
18 watts on the 460 MHz band - in commercial two-way
radio service.
