Tiny Giant
The Tiny Giant is a very small 20W amplifier design by Taylor Livingston based on the TDA7240A chip.
Design
The design uses a 19.5V 4A laptop power supply. This power supply was choosen as it is used by the majority of laptop computers and thus easily available. An 18V supply can also be used by changing a single resistor.
