LOW NOISE GENERAL PURPOSE AUDIO AMPLIFIERS
The BC107, BC108 and BC109 are silicon planar
epitaxial NPN transistors in TO-18 metal case.They
are suitable for use in driver stages, low noise input
stages and signal processing circuits of television
receivers. The complementary PNP types are respectively
the BC177, BC178 and BC179.
