	epanorama.net/Amplifier power
		Power measurement of an amp requires that the amp is properly terminated by Ohmic resistances of nominal value both at input and output.
		If a manufacturer chooses to quote a power rating at 4 ohms in their advertising, the amp must be capable of delivering this much power after a 'warmup' period of operation at 1/3 power (which level actually dissipates _more_ heat in the output stage than full-power operation).
		When you're told a stereo power amplifier can be bridged, that means that it has a provision (by some internal or external switch or jumper) to use its two channels together to make one mono amplifier with 3 to 4 times the power of each channel.

	Audio power - Wikipedia, the free encyclopedia
		The term sine power is used in the specification or measurement of audio amplifiers or loudspeakers.
		A meaningful and reliable measure of the power output of an audio amplifier, or the power handling of a loudspeaker is continuous sine wave power, or more strictly 'continuous average sine wave power'.
		The term RMS is used mistakenly due to the fact that the mean power is calculated from the RMS voltage and current (or one of them and the impedance); power being proportional to the square of voltage or current.

	Audio Power Amplifier
		This simple audio power amplifier was originally designed for a circuit board workshop, conducted by the OSU IEEE Student Group.
		At the workshop, 20 participants each constructed this amplifier, by etching and drilling the single sided circuit board, soldering all components, and attaching a pre-built heatsink assembly with the output transistors.
		A wide range of power transistors will work, but they should be rated for at least 100V, 8A, and 80W power dissipation.
