The 47 should be same base as 46, though operating conditions would vary. Again, as with the 27 and 46, flament is 2.5v at 1.75amp.The 49 is yet another UX5 base, 2v filaments with a filament current of 120mA, so you'd need resistors or something to bring the voltage down from 2.5v to 2v. Pinout is as 46 or 47.
The 24a is a theoretical possibility, though I doubt if it would sound good enough to be worth trying. also UX5 base, 2.5v at 1.75A filaments.
