This is linear power amplifier 2000 Watt which need advance knowledge in electronics since the schematic diagram is very complex for hand made circuit. I think you have to re-design the schematic diagram using circuit diagram software designer such as diptrace, eagle, expresspcb ect. Or just order the PCB online, they will be glad to… Read More »
This is an amplifier circuit with gain music output power up to 7W. It uses IC TDA2003 as main component. This 7 watt audio amplifier circuit is small but powerful multi purpose amplifier. IC TDA2003 provides a high output current capability (up to 3.5A) very low harmonic and cross-over distortion.
This is the circuit diagram of 2 Watt mini audio amplifier. This circuit is inexpensive, easy and quite simple. This is general audio amplifier which can be used for computer, CD player or other devices which have headphone output. The circuit was deliberately designed using no ICs and in a rather old-fashioned manner in order… Read More »
This 200 Watt high quality power audio amplifier will give you top class quality for loudspeaker 4 – 8 ohm. Frequency range 20-20000Hz, Voltage 24-36V with current max 5A. You need heatsink to keep the transistor from overheating. Itu use dual polarity power supply to work, then you may use this power supply to supply… Read More »
This is the scheme diagram of 20 Watt stereo audio amplifier which use dual IC TDA2005, one IC for left channel and the another one for right channel. Each IC will give you 20 watt output, so the output will be 2×20 Watt. The supply voltage for this circuit is 8VDC to 18VDC, use regulated… Read More »
This is 20 watt audio amplifier circuit design which use IC LM1875 as main component. This circuit is simple and very easy to built. For stereo channel, you need to build the two same circuits which will amplify the both of audio channels (right and left channel). Dual polarity / symmetrical power supply required for… Read More »
This is the circuit diagram of power amplifier 45W using power uPC 1230 as the main component. The pre amp head has been added in the circuit using uPC 1032. This is an popular old circuit for hobbysts and the 45 Watt amplifier circuit should be working fine since the PCB already on the market… Read More »
This is a 200W power amplifier circuit project. The circuit features high power, good definition and very low noise. It delivers about 200 watts in 4 ohms loudspeaker: a 4 ohm speaker or two pieces of 8 ohm speakers in parallel. This 200W power amplifier using the complementary transistors of 2SC5200 and 2SA1943 as the… Read More »
This is the simple project of small sound amplifier for ears or often called hearing aid device or hearing loss amplifier. This circuit was already tested on some patients and give significant improvement in the hearing ability to the patients. It consumes a very small amount of power within the range of 10 milliwatts. Furthermore,… Read More »
