This project is a compact stereo Hi-Fi R2R NOS DAC based on two classic Burr-Brown PCM58 18-bit converters, with one DAC chip dedicated to each audio channel.

The generator allows you to create STL files for 3D printing a fully customizable electronic enclosure. By changing the parameters in the source file, you can adjust the enclosure’s properties and adapt it to the specific requirements of your DIY project. The parametric generator is based on an OpenSCAD file in which you can modify parameters such as the enclosure dimensions, the position of the feet, the size and placement of ventilation openings, wall thickness, corner radius, and many other features. As the final output, the generator produces separate STL files for the top and bottom parts of the enclosure, ready for 3D printing.

This project is a low-noise dual-rail linear power supply intended for audio applications, precision analog stages, DAC analog rails, I/V sections, output buffers and other circuits that benefit from very clean and stable ± DC rails

This project is a low-noise linear power supply designed for an audio streamer based on Raspberry Pi 3B+ and also suitable for Raspberry Pi 2B / 3B.

Low-noise 3A DC-DC pre-regulator based on LM2576HVS-ADJ with additional output LC filter This project is a 3A DC-DC buck converter built around the LM2576HVS-ADJ, designed not as a generic standalone switching power supply, but specifically as a pre-regulator for a linear power supply.

Positive LDO based on TPS7A4701 low noise - 4 μVrms drop in replacement for old LM78xx series.

Negative LDO based on TPS7A3301 low noise - 16 μVRMS drop in replacement for old LM79xx series.

This adapter lets you solder two single op-amps in SOIC-8 packages and use them as one dual op-amp that plugs into a DIP-8 (dual) socket.

This PCB is a compact low-noise linear power supply intended for audio applications (DACs, clocks, analog output stages, I/V converters, preamps, active filters, etc.). The main goal is to obtain a very clean DC rail with low 100/120 Hz hum and reduced high-frequency “rectifier dirt” coming from the bridge.

SOIC-8 to DIP-8 Op-Amp Adapter ( 1 : 1 ) in manual breakable panel.

The goal of this project is to improve the linearity of an R-2R DAC based on the PCM58 chip.

This project is a DIY split-rail (±) linear power supply with CRC filter designed for the Musical Fidelity A1 amplifier – a true Class A design with high quiescent current demand. Could be used for any audio power amp with high current demand with split-rail (±).
