You can add CS4329 to the list.😉
There is a National IC DS26C32ATN quad differential line receiver feeding the input to the converter board. This is to switch between the coaxial and optical inputs.

Eddy,
I have a 1541 DAC and I shall try on mine first before I can say OK or not. Please wait as I am having holidays till Jan 7 now.
Your DAC has simple input circuit and direct couple to 1541 DAC chip and should have higher chance BUT I really cannot gurantee 100% successful rate.
Those who has used ok on Thomas' 1541 DAC may share their experience here first. Thank you.

Hi Spencer,
last time we talked about it it seemed that your board wasn't compatible with TDA1541A, but now you report some success with it: can you provide more details?
I'd be interested in using it in my NOS Dac.
Cheers
Andrea
PS The BJTs are arrived.

I have one left, a CS4390-KP EP.
Do contact me if your are intersted, price is upto you, I guess you will know what's reasonable. Cash money will only do (this in euro).

Hi Spencer,
I'm interrested in 2 kits w/o DIR9001.
Do you still have some in stock? 🙂
Thanks,
Trung

Andrea,
I have not able to make it work in my TDA1541 DAC yet but it is one buyer who told me that it is working with a 1541 DAC. Thus I said I am going to try on my 1541 DAC again.
Trung,
Yes still have stock but I am out of HK till Jan 7 and thus will not be able to handle any shipment. Please wait.

As promised, here is the photo how 9001 converter board is used in the TDA1541 DAC.
Notes:
1. The input of the DAC only used a pulse 1:1 transformer couple from the SPDIF signal.
2. 256fs and I2S output mode of the 9001 is used.
Jumper setting are:
J1/J2/J3 short
J4 and J5 open
Enjoy!

Hi Spencer,
I see that the DAC board also has a SAA7220 digital filter.
Does the SAA perform a format conversion or the IIS signal can go (non-os) straight to the TDA?
Cheers
Andrea
I have 5 pcs. each of the three active components required for this board. E-mail me if anyone needs them.
Andrea,
The SAA7220 is used as a 4x oversample digital filter. Without SAA7220, it is NOS. I use SAA7220 because I use jfet IV (similar to pass D1 IV) so that there is less noise if I use 4x over sample. Or best 8x over sample digital filter.

Spencer,
thanks for the reply. Did you try runnung the DAC without the SAA7220?
