This is an unusual name for a valve. Is it Russian or Chinese? P is R
in russian, but Russian doesn't have an S.

There may be a typo in the OP, as 4P1S is a recognized tube type.

The 4P1S appears to be a loktal triode.

I have been trying to find references, I think Arny is right, looking
around I think they could be the same as 4N1N which are not that common
either. I did find a reference that made me think they were pentodes though.

The headphone amp that uses these things might be using triode-connected
pentodes. I found a spec sheet that seemed to be talking about triodes, but
that might have been the usage, not the device. If the 4P1S is based on a
legacy design, every legacy loktal power tube that I can find is either a
rectifier or a pentode.

Do you have one? If so, what base is it?
