The housings are made of anodized aluminum panels and laminated wood processed by milling, staining and varnishing. The front panels are made of aluminum and are inscribed on a CNC. Then they were immersed in a solution of caustic soda, inscribed with ink pen for technical drawing and finally covered with transparent varnish.
 
Hi
posting pics of my very early design, first design Atwater breadboard type amplifier. Plenty of time so I made all calculations, schematics, all hardware, hanwinded the power and output transformer, also made a simple hand winder and so on. To much spare time I guess but I wanted to go deep and understand the whole design process from start to end.

Fabulous DIY work :superman: Congratulations :cheerful:
