他有一些 MOS-FET class A single power stage amplifier
(可惜 電路圖 好像貼不上來,請參考)

他說: Pass laboratory is famous for this method.
This circuit is a little more complicated than theirs.
Class A single amplifier is more precise at low signal level,
because of being free from crossover distortion. September,1996
他另外一個電路,讓我想到可以用dual JFET 重新改造 Aleph-X

剪貼一下mosfet圖的SE輸出,再用到下圖取代這兩BJT,不是就很像類似 JFET+SE MOSFET的Aleph-X 嗎?
我想如果用DT-01、ULTIMA-POWER 架構來改也應該很容易.
