Highly stable circuit uses easily obtainable components. Transistor types are not critical. Shortdrcuit protection is provided by constantcurrent source D1-Tr2-Tr5-Tr4. Output transistors Tr5 and Tr6 requirb heatsinks ca pable of dissipating at least four times rated output power. D1 and Tr2 should be in thermal contact.-A. H. Calvert, Class A Power Ampli-fier, Wireless World, June 1976, p 71.
