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.
So does somebody knows the specs or a replacement for this transistor ?
Maybe I don't understand what you're asking, but the replacement for a
2N2222 is a 2N2222. They're still made, and not at all hard to find.
If that's not what you're trying to replace, what is the part number
you're replacing? I could be wrong, but QP1008 looks like a component
designator, not a part number. Even if there's only an HP part number
(e.g., 181x-xxxx), that's more useful for finding a replacement than
a component designator.
