I configured the Zen in the following manner:
Power BOARD-
AC 22V/2, SAMWHA 10000Uf/35V as C1/C2.
AMP BOARD-
Wima MKT-2 4.7uF/100V as C2 and Ninchicon Golden-4 100uF/63V as C1/C3
NICHICON-2 2200Uf/40V as C6
MY homeland’s matel RED series resistors
IRF610-4 Q1/Q2
C1815-2 as Q3
Gold-Plated RCA input jacks
ALPS BLUE volume
Original 3.5mm Jack output
A A4 Paper size, height 5 cm .

Listen to sense OP amplifier voice fashionable, have passion relatively tentatively. But the sound disturbs , do not hear long.
ZEN make warm, balance stage,can very fine drive HD495 headphone of me, remedy tiny voice it .
Wait a moment I will put the inside picture of ZEN to , make a POST for the first time, thank everybody for paying close attention to .
I spend a weekend on studying ExpressPCB (Ver3.2.0).This is my PCB work.

by the way.I english so poor,Meaning that sometimes expresses may misunderstand , I will make great efforts to improve own English level.
This is my AMP for the first time runin test ( unit V):
LEFT channel:
Vr18 =1.575;
Q3,b =11,c =17,e =12;
Q2,g =4.8,d =12.3,s =0.6;
Q1,g =17,d =20,s =13.
RIGHT channel,
Vr18 =1. 625;
Q3,b =9.5,c =14.5,e =10;
Q2,g =4.6,d =10.5,s =0.6;
Q1,g =14.5,d =20,s
Bias current of about 0.27A.
Looks like everything's working. But there's a difference in the DC bias point. Check R9/R14 on the left channel (and remember R9/R7 also set the gain).
This is the inside main board (double mono).

The single amp SCH.
