Building the ultimate NOS DAC using TDA1541A

[Jean-Charles]

Hi Max, Sylvain and everybody.

No, I did not assemble John's dac yet. It will come for sure.

It was Thomas's dac (Tube Lover).
Sylvain got confused here may be. We had an excellent night.

Sylvain, I am working on a tube output for this dac. Should be ready in a few days.

Adhoc, very well said. May be some of the more "learned" members who needs to brush up on their manners should take Adhoc's reasonable suggestion to heart. I wouldn't hold it against anyone on this board if he or she had no idea that the olfactory system can perform hierarchical categorization of odors or how the somatorsensory map of the postcentral gyrus is layed out. I certainly don't feel superior because of it, and I would be happy to explain it in private email if someone was interested.

MGH, beware what you type, i studied for my first-line healthcare job too!

Hi Adhoc;
Well said. ( Good to see more coleagues here )

Then again, lets not focus on this topic ethernally... too noisy.
I'm sure our more knowledgeable mates are great guys and we surelly would have a great time listening to some music and drinking spirituous beverages toghether. Also, they certainly are a fountain of digital wisdom (and I am not being ironical at all). The problems are:

a) style of posts (wich could be more diplomatic (and well intentioned. Ooops!)).
b) given their skills, they could easily test the proposed project and discard good performance. That, in the hypothetical case that they grant the benefit of the doubt...

Humbly yours,
M

PS: so tubelover's DAC was it. Good to know.
PS2: I don't see tubelover's TDA1541A groupbuy anymore...someone knows where is it?

hi max,


directly email to me will be Ok.

hi john,

U paid too much effort for his DAC.
Big Thumb for U.


hi all,

In my opinions as adhoc,

we all enjoy diy, Do it yourself, pls less noisy I thought we all love this forum, pls use your effort to protect for it..


The last that I like to say was I saw some message claimed that some ebayers was sold their clone parts in ebay which was made In CHINA. Such as Nelson & others design. That's why I suggested john not to send his files to china to produce PCB's. I understood that PCB made by Oversea's factory all Diyer will pay more. But lf U considerate john paid much effort day by day to test, design. I thought we must support for him. Otherwise all items were copy, copy, copy. Nobody will like to share their point of view & design too.


thx

Hi

I have 5 Philips CD104's
Three of them I have modificated to NOS (removing SAA 7030
and puting SAA7000 in 14 bit mode by setting pin 16 high)

I realy like this thread started by ECDESIGNS

His DAC uses I2S (dataline = L+R) and pin 27 on the TDA1541A is high (+5v).

The cd104 has no I2S but DLCF and DRCf separate.
To use that with the TDA1541A (I have a bunch of S1's)
pin 27 has to be low (-5v) placing the TDA1541A in simultaneous L and R data mode

I want to use this NOS DAC (no filtering !!!).
Is this possible with separate simultaneous L and R datamode looking at inverting data and or WS to the second or furter odd TDA1541A.

Thanks in advance for looking at this.

How many TDA1541's do you plan to use?

This is an honest point of view, Thomas.

but....

I have to admit I was hoping you'd offer to have the PCBs made at your friends factory ( the vga card manufacturer ). Your boards look stunning !
