The MPF102 JFET is a popular N-Channel JFET that is commonly used in low power amplifier circuits. The JFET is no longer in production and finding it might be difficult. So they are not recommended for new designs.
The NTE159M is a general purpose PNP transistor with a maximum gain of 300 and collector current of 600mA. It has a low collector saturation voltage of 1V and can be used in switching and amplifier circuits.
