How about a 7F8 loktal? Dual triode for VHF use. u~48 but gm~3000 so not close to a DJ8 (~12,000) in that regard. Interesting construction on the ones I've seen; the triodes were mounted horizontally at the base so very little structure was visible above the base. Looked empty.

thanks for the tip. Have you made any amps with that tube?
Never made anything that used them in audio app. Bought a pair years ago to experiment and promptly misplaced them. Also, personal experience with repurposed RF tubes such as 6DJ8, 12AU7, 6C4 etc is mixed. As always, YMMV.
