Product Description

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 micro-conduction 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 4-12V
Speaker: 0.5W-10W
Circuit 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:

10 x DIY OTL Discrete Component Power Amplifier Kit
