AD811 as I/V stage for current DACs (and test some other opamps including Burson Audio opamps as I/V)

Ahaha rigth, you are wise !

Whatever he is born 7 years before zero and more in spring times . Damnit they swapped out celtic fests ! In 50 years there will be a Tesla fest the 25 !

Cheers Ernst. Best.

Sorry Grunf if you feel my inputs don't belong here, I am sure you're a good guy whatever I am not agreeing with some of your points of view exposed as verities. It is not against you. It is more than I am looking for the best as well.
 
You mean the best ECC88 comes from your country and you discovered the AD811 back ??? 😉 😉
Messiah in Traban syndrom. (it is not the MIT school...)

We know where is Greenwhich since Mariah Carrey ! Lol !

off topic joke for the mood !

I made an AD811 DAC to listen my fav Mariah Carrey (carré in french means "square", which is funny when you look at that woman).

So the tune was good but there was something a little veilled in her voice and then I putt a tantalum, it was much better, almost near as the original live :


Btw this guy is a real Oud player guy
 
yes you're rigth the origin meridian seems to look more and more like this from your side point of view, but i still look for open eyes:😆😛
Maybe I found the tantalum....

So anyway,, if Vunce want I publish a gerber with the foot print for your tantalum, it is okay for me to offer that for christmass if I have the files,, it should be fast with Kickad in relation to what he uses as CAD prg. I use Kickad 8.

I'll try to enhance some things due to the fact the ad1862 is too far anyway from the load.

After of course you putt the pcb in your system where it belongs !

I said there's no need, the schemes are mine and I don't think you deserve them ,not even for Christmas,.
 
oH I just reacted to the look of your video ! 😉

Me in real life is a little more rafinovanné ! But I can adapt fastly !

I don't need you to make a pcb better as you do, while I recon I like the way you do it DIY. (I think there is some good in thicker ground for evident reason but you should more use not interupted ground plane, you surely have habits from your tube period,, I believe)
As you ask someone to adapt the Vunce pcb he offers (in PM he offered iirc) I can adapt it,, I will not use it, but if I wanted to do so I could have been made on pcb with best layout than your dac you showed with Super Regs at long distance of the DAC core !

"I said there's no need, the schemes are mine and I don't think you deserve them"

here is your true face

... and I'm a child 😉 !

My offer is honnest, I think we both share the mantra "best for the people" !

It seems we don't share the same mantra. I'm sorry.
 
same same but different, lol !

Indeed I'm living in a civilised town ! Better than "worse for the people" then 😉 And as the scheme is public (I don't talk of secrets) because this is what we talk, I have hard time to understand what your are saying as if you was the big boy in red. Oh for sure, at the view of what I seen I don't want your secret sauce, sorry too !

Anyway Vunce has the offer, I don't care. He will probably adapt it for himself and for other if his "friend" having time.

Oh man I do know to recognize true mens with true words in our world whereever the meridian is.... Don't be afraid to me! 🙂

But you deserve my best NYD offer anyway 🙂

Are you thinking of Vunce's PCB?
We are on the same path, and I also plan to put my PCM1794 into operation this year. The PCB with the PCM1794 will be mine so I can place small shunt regulators right next to them. I'm just still thinking whether to put the four AD811s on the same PCB or separately so I can do tests.
Was thinking about the little neat hand drawn pcb which you posted earlier on this thread, but at the moment it's too early and remaining open to possibilities. I am not familiar at all with tools for etching pcbs..
 
At geoturbo, it is files you send to à manufacturer that makes the pcp for you: cheap.
But the pcb needs correction according chip film resistors and caps around the op amp new old finds. This is what Grunf inputed. But à very well known thing about fast op amps layout already. Just jet lag correction. If the tantalum is too expensive, choose good Vishay smd.
The file was made by Vunce member avialable on request.

Think as well to the good opa1633 diferential as I/V here for the pcm179x 😉. Some don't know it behind the wall !
