I aquired a HP 9816 with a faulty power supply.
Thanks to the diagrams of Tony I found out that the switching transistor
QP1008 is shorted and a 2n2222 but thats no problem.
I googled for it and searched my datbooks but can't find any replacement or
datasheet for it.
Uhm, a 2N2222 is incredibly common, and is pretty much just a generic
NPN small-signal tranny.
Use anything. Unless of course Tony points out some clever idiosyncrasy
that makes it the only part to use here ;-)
