Drive transistors. BC548C instead of 2SC3198 (BC237), instead of 2SA1266 BC558C (BC307C) can use. Output transistors from low to high, depending on the supply voltage TIP3055-TIP2955, BD911-BD912,-2SB688 2SD718, 2SC5200-2SA1943, BD249C-BD250C be used as a conjugate. Circuit of the original supply voltage + / – 35V CAR POWER AMP and PAS-4100. 2 channel has been designed by me.
2-channel and 4-channel as a tried and used in front of a crystal-clear sound seamlessly with LPF performance was solid. .2 X 220W 18V transformer with a 4 channel version without fainting and cut me personally was pleased. 8 bridge diode, the + and – ends of two pieces is enough to feed 3,300 Mf 50V capacitor. As shown in scheme-1 4558 (SIP9 casing) to which a rare TA755558S was used instead.
100W Amplifier Circuit the finished
PCBs, as shown on the pictures and the relay is located behind the 3-pin female con PCBs. (Delay IN) to end the R and L terminals on both channels on the output line at the tip of G (medium-end) will be soldered to the GND line. Number 10 is a circuit in terms of cost-performance I would recommend.
Important: In the diagram, as shown by the 4 and 6 which pins are + input as çizilmiştir.ancak a watchful eye is necessary in the diagram No. 7 pin to connect via as shown Actually 4 and No. 6 pins + input terminals to the signal input 3 and 7 of the pins in – login R + C-shaped ends is to give to the GND line. )
