I am not familiar with that tube. If it has enough capability, it could very well serve as an amplifier. I suspect we are talking about milliwatts here, which of course is fine for headphones. I don't anticipate much gain, as the transconductance wouldn't be very high. Of course, if the signal from the crystal set is weak, this could help.

Actually, I sense that you are just anxious to play with this stuff, and of course that's just fine. Make sure you don't damage the tube with too much current.
