Gomi,
Landoctor,
Samoloko.

Chungtat has just posted the manuals that I have. Mine are in Chineese too, so I will not duplicate the information.
There are translators online that can help. Google and Yahoo are free.
I have a few diagrams. I include 5, this is the maximum I can upload with this post. I will complete with the next.

As a general information, I will refer you to post 1930 and 1932 and all others before and after.
I gave a list back then of other posts that could be of interest for diagrams and settings.
I saw Gomi and Donovan there too.
Thomas is not available anymore, but I found something very interesting.
Search in Google for a commercial product called: Satch DAC.
This is Thomas's dac right there.
So I beleive Thomas has turned commercial. Anyway, with further reseaches on Satch dac, you may find pertinent informations to help you with your present dac. Let us know what you find.

Hi Jean,

Appreciate if you can send me a copy
samshlim at yahoo.co.nz

Also, have you tried the fix suggested by ecdesigns?
I am stuck with the pin numbering. His inst:

*---
SN74HC04 could be used for this, SN74HC04 pin numbering, notch to the top, top view:

pin top left is pin1, next one down is pin 2, and so on, until pin 7 (bottom left)
pin8 (bottom right), next one up is pin9 and so on, until pin14 (top right) .

ADDING THE INVERTER:
> Connect GND (SAA7220 socket pin 12) to the following pins of the SN74HC04: pin3, pin5, pin7, pin9, pin11, and pin13.
> Connect VCC (SAA7220 socket pin24) to SN74HC04 pin 14.
> Solder a 100nF decoupling capacitor between SN74HC04 pin7 and pin14.
> Connect pin1 of SN74HC04 to pin3 of J28 (DATA).
> Connect pin2 of SN74HC04 to pin3 of J25 (Inverted DATA).

John

*-----
Well, The SN74HC04 that come with the Thomas DAC is 16 pin version not 14. Do you know how to to apply ecdesigns fix to a 16 pin version?

Appreciate your help.
