***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
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 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/).

TDA7439 + NodeMCU + Aptx module audio board
OLD version, noisy.
New version with ground separation: (https://easyeda.com/fxndstrs/tda7439)
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.
