Soekris dam1021 R2R with Tube Buffer

花了很多時間和汗水, 多次的失敗, 終於做好這次DAC了.


我用兩件Soekris dam1021 rev2, 可以XLR輸出沒有經過膽, 也可以RCA經膽buffer輸出

 
字上埋色
 
  Soekris R2R 主要用 shunt regulator 供電, 除了R2R ladder 我用了 lifepo4 電池供電. 頂板是用了半透明亞加力板, 本來是密封只留孔插膽, 後來發覺長開後箱內較熱, 於是我在頂板開了孔助散熱, 也把電池外置, 令它們不受箱內温度影響

    Hi,

    I'm building a Soekris DAC myself and i'd want to know more about the tube buffer stage that you have implemented here. Many thanks
