8 Ohm 4 Ohm 125W 200w power amplifier circuit transistor is a quality two channel stereo mono single channel if you want to use the same circuit must log 2 toroid transformer used supply section
Power transformer I gave wound on order and is the primary coils of 230V, the seconder and two windings Monday 40Vac 7A and coils 13Vac 0.5 A, which is used for power protection for the speakers. I gave Gladilne capacitors 4, each of 10000uF, 80V. In the case of transistors Q1 and Q2, I added a trimer potentiometer value 100E, which serves to adjust the offset voltage at the output. When transistors 2N5551 and 1N5401, note the order of feet, because it is different than for example, transistors BC547 and the like.
The final transistors they are installed on aluminjast 50 x 50 to be served in almost every hardware, housings are insulated from the profil.
