50W POWER AMPLIFIER WITH IC TDA7294 CIRCUIT SCHEMATIC DIAGRAM
With the addition of a handful of parts and a suitable power supply, this module will deliver over 50W RMS into 4 or 8 ohms with < 0.1% Total Harmonic Distortion (THD) and < 0.1% Intermodulation Distortion (IMD). A similar circuit was published in Elektor magazine, 11/96.
It is also suitable as a replacement power amp stage, or upgrade for many existing amplifiers of between 30W-50W, provided they have a suitable dual supply, and most do.
