DIY Projects

Gainclone projects have been described extensively in the past and there is no point in repeating what is written elsewhere.The

This project is quite old (probably dated late 1980s) and has been created before it was common to use a

Features: 2 x 25 W @ 8 Ohms in Class-A (1,25A bias current) 4 transformer-coupled inputs (2 balanced, 2 single-ended),

Features: Push-pull output stage to control the motor Fixed voltage regulator used as reference Designed to use the original Verdier

Features: Preamp designed for MC cartridges (Denon® DL103, EMT® TSD15, etc.) Each amp driven by it’s own pair of 12V/6AH

Features: Modular DAC Plug-in modules for complete digital signal path 6 positive (4 digital + 2 analog)  power supplies 4

Features: Modular 24/96 Sigma-Delta-DAC Plug-in modules for digital input receiver and digital analog converter Inherent jitter reduction through sample rate

I wanted to be able to compare different DAC chips under the same conditions. Therefore the next DAC I was

With this design I wanted to try how far you can go with a CS4328 Sigma-Delta-converter and a single ended,

This is my first own design after I have build an Elektor® DAC (PCM63) which I didn’t find very satisfactory.
