The schematic diagram looks crowded because it is this power amplifier project is populated with 33 transistors. Here’s a brief description of the circuit: The project includes six pairs of complementary 17A/250V/130W TO3P power transistors that features wide SOA for reliable operation and excellent gain linearity for low THD from Fairchild Semiconductor. The project’s prototype produces 45.62Vrms across an 8Ω load or a power output of 260 watts with ☘0VDC power supply rails. Project 44 features a complementary differential input stage, a symmetrical cascode voltage amplifier stage and a three-stage emitter-follower output stage. Project 44 will be the penultimate complementary differential input stage or mirror-image topology project. So far, several complementary differential input stage or mirror-image topology power amplifier projects have been presented.
