***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
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...
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/).

**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...
Redesign Mini Subwoofer STA540 + Tone Control, Project pertama aku yang di publish. Versi SMD sedang dalam proses. Jika ingin memberikan saran dan kritik dipersilahkan, maklum masih newbie
> IC STA540
> DC 12-20V 4A
> AC 9-15V 4A
> 2X 11W + 1X 38W 4OHM
> 2X 7W + 1X 20W 8OHM
> Resistor 1/4W 5%
R1, R3 = 2.7K
R2 = 3.3K
R4, R11, R13 = 47K
R5, R12, R15, R19, R20 = 8.2K
R6, R7 = 1K
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.
