Audio Note DAC KIT1.2 component list and power transformer spec

[PTSOUNDLAB]

Hello,

I have schematic of Audio Note DAC KIT 1.2 but some values missing (unreadable). I need values of these components if someone have part component list, could you give me some help ?:

1) Power transformer secondary specifications (Volts and amp)

2) Power supply stage: values or component name of V1, V2, V3, L8, C10, C2, R1, D1-D2 fil rectifier, D3-D5-D7-D8 diodes 10V rectifier, Led1

3) Analogue output: values of C13, R13 and what is J1-J2-J3-J4 ?

4) Regulator : Values of D12, R21-R22-R24 and component name of U2, Q1, Q2

Thank you very much boys 😉 ...... ok my english is not good, but i'm french, sorry 🙄

Pascal.

Hi Pascal,
I am sorry I did not posses a better copy (je suis désolé).
1) I have no idea

2)
V1 & V2 appear to be a neon tube, some overvoltage protection. V3= 6X4WA
L8 15H/30mA
C10 35µF/500V
C2 100nF400V
R1 121 Ohm
D1, D2: 31DQ04
D3, 5, 7 ,8 : 11DQ04
LED green

3)
C13 470nF/630V (this is a paper in oil cap)

R13 1M
J= jumperwire= 0 Ohm

4) Regulator
D12= red LED
U2 & U4 LF351
R21 3k48
R22 3k48
R24 2k0
Q1 ZTZ449
Q3 ZTX449
Q2 ZTX549
Anyone has a better copy?😕
Edit I corrected value of C10

Hi Elso,

(ne sois pas désolé 😉

thank you for all

Cordialement.
