The CTA low distortion audio power amplifiers home

The Euraudio CTA low distortion audio amplifier family consists of three audiophile grade audio power amplifier DiY kits, which are recommended for hobbyists interested in DIY audio.

These are based on the CTA12 and CTA14/CTA14A Low distortion audio power amplifiers, which are cheaper and simpler versions of the LDA14 and LDA17 ultra low distortion high-end power amplifiers. In fact the CTA12 is much cheaper.
