How about going for an equivalent type, like the  CZT3904 from Central Semi?
Mouser seems to have 200 of them on stock[1]. I have not used something
from Central Semi so far, so I don't know their production quality.
But guessing from the circuit of the TNS-BUF, it's not too critical.

BTW: The transistors in the schematic of the TNS-BUF manual are
inconsitently marked.
