200W Stereo High Power Amplifier LM3886
The LM3886 circuit is in a non-inverted configuration, so the input impedance is determined by the input resistor R1, i.e. 47k. The 680 ohm and 470pF resistor capacitor filter network is used to filter out the high frequency noise at the RCA input. The 220pF C4 and C8 capacitors are used to shot out the high frequency noise at the LM3886 input pins.![]() |
| LM3886 Power Amplifier Schematics |
The PCB is designed in a way that the power ground is separated from the signal ground, as you can see from the below layout. The signal ground is located in the middle and surrounded by the power ground. There is a thin trace near C5 connecting them. The PCB layout is done by using PADS PowerPCB 5.0. I think it is a powerful layout software.

The power supply used is a regulated power supply. I used 10000uF per rail before the LT1083 regulator. After the regulator, I have 100uF on the regulator board. The advantage of using regulator is that the power supply ripple voltage is removed. If power regulation is not used, I can hear very little 50/100Hz hum from the speaker.
The high current MUR860 diode is used to ensure high current flow. The voltage regulator used is LT1083, it can provide about 8A of current. Transformer used here is a 500VA 2x 25V. The power supply is then regulated by 2 LT1083, after the regulation, the voltage is 30V.

The sound of this amplifier is similar to my LM3875 amplifier, which is very clean and detail. It has no hum, no hiss and no noise. Compared to the LM3875 Gainclone, this amp can deliver twice the power to my 4-ohm speaker, and it improves the dynamics and bass punch a lot.

Stereo tone control with loudness and filter
Tone control circuit is used to adjust the tones before entering the amplifier. Tone control over equipped with a loudness and filter directly without using the switch to disconnected or connected. Part of his filter that is C1 and R1 from ground to input , and for his loudness on the R4 and C3 are connected to the input and then go to VR1. C2 and R3 go from ground to the input . After the input is set by volume or VR1 then procesed again by treebel ie C8 , R13 , R14 , and VR2 . Bass on R10 , R11, R12 , C7 ,C8 , and VR3. For supply voltages has been given a stabilization in Q3. See schematic below :

Creating a stereo amplifier with TDA2003

Here I make a stereo power amplifier with IC TDA2003, but actually i made it with 2 IC , so that a stereo amplifier . Construction is very simple and easy. I only need 2 TDA2003 mono amplifier circuit , and then combined into one.Then the transformer , the transformer that i use here is the transformer 10A , so that the power released is greater. Grid power amplifier using the former from the box 10A adaptor , :-) decent can still be used . To view the location of components inside the box , see below :

Car Stereo Audio Amplifier with TDA1553CQ Circuit Diagram
Car Stereo Audio Amplifier with TDA1553CQ Circuit DiagramThis is a stereo audio amplifier for your car. The ambit is powered by a distinct IC TDA1553 with some alien components, this IC will handle your stereo car audio system.
The TDA1553CQ is a caked chip class-B achievement amplifier in a 13-lead artificial DIL-bent-SIL ability package. It contains 2×22 W amplifiers in BTL configuration. The accessory is primarily developed for car radio applications.
Special features of the device are:
3-state mode switch
· standby: low supply current (<100>
Loudspeaker protection
When a short-circuit to ground occurs, which forces a DC voltage across the loudspeaker of >= V, a built-in protection circuit becomes active and limits the DC voltage across the loudspeaker to <= V. Pin 12 detects the status of the protection circuit (e.g. for diagnostic purposes).
Short-circuit protection
If any output is short-circuited to ground during the standby mode, it becomes impossible to switch the circuit to the mute or operating condition. In this event the supply current will be limited to a few milliamps.

120W Stereo Amplifier using STK4241V
This amplifier circuit is ideal for audio devices for home supply. STK4241V amplifier specifications might lead one to believe that you can use supply voltages of ± 78V. With zero input signal (and therefore no way out) I could, but I would not recommend anything better than ± 45V 8-ohm loads, if expected, although ± 54V will be fine if you can provide a good heat sink.
