The A40 Power Amplifier (c) Nelson PassPass Project: A40page 1 FLATTERED BY THE opportunity to publish a project circuit, thedesigner is often beset by seemingly contradictory considerations. Onthe one hand, it is tempting to design a complex circuit as ademonstration of technical prowess; an Amplifier with large numbers ofesoteric components performing obscure functions. Such an amplifiermight be a smorgasbord of electronic technique, featuring class Aoperation, cascoding, constant current sources, current mirrors, andextra-loop error correction. It would be fascinating to build and perhapswould also sound good. On the other hand, complexity is not a good end in itself and a muchsimpler circuit would suit the needs of the amateur more ideally for lowcost, high reliability, and easy construction.
