One may purchase a PNP transistor from a local electronics hobby shop or a chain such as Radio Shack. The website "Mouser" also has transistors and downloadable data sheets for them.

Here's a simple one:
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
a thyristor can be considered as two complementary transistors , one pnp- transistor, and other npn transistor
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
it doesn't have to be. depends on design of amplifier using transistor.
