Let’s take a closer look at how NPN and PNP transistors work. There are two main types of transistor: bipolar junction transistors (BJTs) and field effect transistors (FETs).

There are also certain amplifier configurations that need PNP units. Like an NPN transistor, a PNP can operate in saturation, linear operation, reverse active, or it can be cut off.

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs ...

He does explain why PNP transistors don’t perform as well as corresponding NPN transistors, but they are still necessary sometimes. Once you get used to it, they are no problem to handle at all.

In the circuits given here we use four transistors for the NPN version of the high gain transistor and four the the PNP one. By choosing the best values for R1, R3 and R4 the total current ...

The transistors used (a 2N3055 npn and 2N2955 pnp in TO-220 packages) are reasonably good choices. They should be placed on a heat sink for good heat dissipation.
