This dimmer for incandescent lamps was obtained from an American 1990s documentation. The circuit accepts triac-like loads that can be virtually any type. Triac must be fitted with a heat sink.
It can be obtained from Mouser Electronics new superFETs III from Fairchild for voltages of 700 V...
The fraction of watt amplifier shown can be powered by voltages from 6 to 9 V. It is not...
This traditional complementary symmetry circuit was found in an old documentation, but it can...
