---

With a fully symmetrical double differential input structure, the input tube with.
High-dedicated A42, A92 on the tube, and constant current source constant.
Operational point, the sound quality is very delicate, sound field is very good.
Use PASS machine special high-power FET IRFP240 IRFP9240 output,
Sound closer to the tube, low frequency full of human voice moist.
In the AC35X2 voltage, the maximum output of 100 W 8 Europe, compared to.
LM3886 68W-4 Europe 40W-8 Europe, the driving force is not a level, pay attention.
To TDA7293 100 W is 4 oh test. 8 europe no more than 60 W, even in the AC26, The output can reach 80 W 8 Europe.
Is a piece, can be DIY version.
