This high current regulator with low voltage drop was found in the datasheet of the used integrated circuit itself. The transistor accepts an equivalent and must be provided with a heat sink.
This circuit, discussed elsewhere on this site, is only for incandescent lamps. The frequency...
In the figure we have the astable configuration for the 4093 that serves as a clock for...
This circuit was found in Motorola documentation from 1966. The lamps are according to power and...
