The D3a phono and 10Y line stages are my best selling units. Earlier this month I showed the assembly steps of power supplies for such preamps. Here some photos of the completed units.
The line stage is finished with black anodised metal plates in teak wood.
The phono comes with gold anodised metal plates in smoked eucalyptus.
Drop me an email if you want me to build one of these or any other of my amp designs for you.
