***SONICA 1 - Headphone Amplifier with TPA6120***
Sonica 1 is a rebirth of an older design of mine. A few years back I designed a small PCB for a headphone amplifier, based on BurrBrown (TI)TPA6120A2 chip amplifier. I made a power supply on a piece of test PCB with a toroidal transformer. The end result was quite pleasing and I have used it since then as my main source for music at home, whenever...
This is a 12V Tube Amplifier with a built in USB DAC. The amplifier part is based on Rogers Gomez's [NP-100v12](https://diyaudioprojects.com/Solid/12AU7-IRF510-LM317-Headamp/). The USB DAC is inspired by Jan-Erik Skata's [JEDAC](http://users.abo.fi/jskata/JEDAC/).

Class-A Headphone Amplifier using IRF610 and LM317 as CCS.
The original project and overall idea is to [this guy].
Note: Only one channel is shown.Please, also note that the 100k trimmer resistor should be adjusted - see diyaudioprojects.com for more information about that.
Be careful when connecting LM317 and IR...
This is a miniature 0.7W amplifier with adjustable bass boost, gain, and volume controls. Uses 1/8" (3.5mm) headphone jacks on the input and output. Powered by USB or 9v (4-12 VDC, max of 15 VDC). I designed it to use film capacitors and Nichicon audio grade electrolytic capacitors wherever possible in order to preserve the signal and reduce noise. An isolated power supply such as a battery is...

**Circuit power audio amplifier IC TPA3116D2 D Class.**
The TPA3116D2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω in mono. The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB. The TPA3118D2 can even run 2 × 30 W / 8 Ω without heat sink on a dual layer PCB. If even higher power is needed...

Amplifier stereo 80 watt (2x40) dengan power supply 12 volt. dengan speaker 4 ohm.
- pin 1 dan 13 dari TDA8560Q adaah input sinyal audio. kapasitor 474 bertugas melindungi input dari arus DC yang masuk.
- pin 3 dan 10 adalah supply tegangan. jika tegangan lebih dari 18 volt maka sirkuit tidak ON.
- pin 11...
If you need to have a high power amplifier in small size. I suggest this project, It has powered drive output up 30 watts, with low noise and Low distortion. Read more : [**LM1875 amplifier circuit 30 watts**](https://www.eleccircuit.com/tiny-30-watts-otl-amplifier-using-lm1875/)
