TRANSISTORS
Transistors are used
to amplify electrical
signals. They have
a square tab on
one side. Be sure to
match the tab to the
outlined tab shown
on the circuit board
when installing.
INTEGRATED CIRCUITS
Integrated circuits are
complex, tiny, self-
contained collections
of components that
contain a complete
circuit. Op-amps, audio
processors, and linear
voltage regulators are
three kinds of
integrated circuits.
DIODES
Diodes are used where you want electricity to ow in
only one direction, such as power rectication, and
also to limit how much current can ow, to create
“clipping” distortion.
Diodes are also polarized, so they need to be installed
in the correct orientation. The stripe around one end
marks the negative (minus) lead of the diode. On the
circuit board, the printed outline of the diodes also
shows this stripe. Install each diode so that its stripe
matches the direction shown on the circuit board.
