***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...

Class-A Mosfet Headphone Amplifier
El TDA2003 es un amplificador económico que provee hasta 3.5A de corriente en su salida. Además de usar pocos componentes alrededor de el.
Puede usarse con el radio de un auto o con bocinas de mediana capacidad.
THIS IS AN SMD LM386 CIRCUIT. IT CAN BE USED LIKE A WALKIE TALKIE BUT WITH A MUCH MORE CLEAR SOUND.CONNECT A ELECTRET CONDENSOR MICTO THE "IN" PIN AND "GND" AND FIX A SPEAKER TO THE OUTPUT END.(IF U WANT, CONNECT A LONG WIRE TO THE MIC OR SPEAKER) AND SPEAK THROUGH THE MIC.ITS A REAL FUN AND CHEAP CIRCUIT TO PLAY WITH.
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...
