Electronics Help Care Amplifier circuit diagram This is an amplifier driver circuit diagram. It’s a driver circuit diagram. We can use 2 transistors in this circuit. Here, small driver transistors are used. For 4 transistors or more, we have to use another powerful driver transistor. Here, C2229 is used for the positive driver transistors. and A949 for negative. If we use more than 2 transistors, then we have to change those driver transistors. like C2073 and A940.
We can use a 25-0-25 voltage to a 50-0-50 voltage in this circuit board. It’s a mono amplifier circuit diagram. The output watts depend on the Voltage and the amperes. For 2 transistors, we can use 3 amperes. If we use 35-0-35 voltage and 3 amperes. The output watts will be 35X3= 105 watts.
Like this, we can use another PNP and NPN transistors.
C5198 and A1941 transistors are used. Any kind of PNP and NPN transistors can be used here, positive or negative, and a ground voltage is needed in this circuit.
- C5198 is a PNP transistor
- Collector-Emitter Voltage (Vce): 230V
- Collector Current (Ic): 15A
- Power Dissipation (Pc): 150W
- Gain (hFE): 55 – 160
- A1941 is a NPN transistor
- Collector-Emitter Voltage (Vce): 230V
- Collector Current (Ic): 15A
- Power Dissipation (Pc): 150W
- Gain (hFE): 55 – 160
It’s so easy amplifier driver circuit board.
This is an audio equalizer circuit diagram for an amplifier. Every amplifier needs this type of circuit board. Here, we get 4 volumes for the main volume. one for the bass volume. one for the mid-range. another one for the treble volume. It’s a mono circuit diagram board. A stereo needs a dual circuit board.
