This receiver operates on the same principle as 40W / 2 ohm (24W / 4 ohms) bridge power amplifier. It is simple to perform and works with a single power supply of 18 V. It is based on the use of two amplifiers type TDA2002 is able alone to deliver a power of several watts.
Mounted in the bridge, the two circuits can deliver a comfortable power over 10 W effective on a HP impedance 4 ohms, with a distortion less than 1% (if we accept a larger distortion, the power can rise to 20 W).
