  • Hi Radhu,

    Thanks for your interest.

    First of all, this approach is quite expensive and time consuming. (Honestly, I wouldn't start it, if I knew that it would turn to be that complex).

    You have to be prepared to spend around $2000 for parts and match to 1-2% two pairs of tubes at 3-5 points (at least).

    The idea of this post was to show an alternative approach to high fidelity DAC design: omitting some parts (like filters) and still have a great result.

    So, apart from digital board, no documentation (adjustment instructions or complete set of schematics) was made.
