3pcs DIY OTL Discrete Component Power Amplifier Kit Electronic Production Kit

Description Q1 is an excitation amplifier which gives enough driving signal to the output stage of power amplification R1 and RP2 are the bias resistors of Q1 R3 D1 and RP3 are connected in series on Q1 collector circuit to provide bias for Q3 so that it can be in the microconduction state in static state to eliminate cross over distortion C3 is the damping capacitor to eliminate the self excitation that the circuit may produce 2 Q3 is a complementary symmetrical push pull power amplifier which constitutes the output stage of power amplification C2 and R4 are bootstrap circuits and R4 are current limiting resistors Input voltage DC 4 9VSpeaker 0 5W 10WCircuit board size 4 6 x 3 7CM The circuit is a classical analog electronic circuit which is full of knowledge and fun to make Package Included 3 x DIY OTL Discrete Component Power Amplifier Kit
