Thanks, Attila. Interesting that that part didn't show up when I was
searching for substitutes. I'll look into those.
Yes, the TNS-BUF schematic has a disconnect between assigned part
numbers and the notes. That's fixed in the revised version I'll upload
one of these days.

I need to find 150+ pieces of transistor type PZT3904T1G, SOT223 package
(with heatsink tab), equivalent to Digikey PZT3904T1G0SCT-ND.
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.
