Since audio electronics presence, an audio transformer has played an important role. When the transformer compared with modern electronic components it will look big, heavy, and expensive but it continues to be the most effective in the solution of many audio applications. The usefulness of transformers lies in the fact that can be transferred electrical energy from one circuit to another without a direct connection.

Quartz is known as passive component, which is unique to vibrate (resonate) at a frequency that is very specific and very stable. Usually used for the oscillator, clock, counter, frequency counter, and generally any equipment that temporal precision is important. Quartz can also be used in the production of filters with narrow bandwidth rejector and high rejection ratio.

Mica insulators is sometimes used to isolate a single component of the heatsink, for example in cases where multiple components share the same heatsink, and this component must be isolated from one another (base metals or triac transistor can be connected to one electrode component).
