Thanks 🙂
I thought I had looked there already...
Edit: I looked just now and Mouser seems to have 0 in stock as well.

At the time my friend ordered from digikey on my behalf, they had 7pcs in stock...he later got an email about the one on backorder. This was a couple of weeks ago as well.
According to the digikey website they will have some in stock on the 23rd of October.
Yes, my friend (Torchwood-something here on DiyA) told me that.
Hopefully he'll get them, and get them sent to me before he goes in for surgery on the 30th.
After that, it'll be a while before he does much more than rest I think.
Hi Pistollero,
Im planning on the same setup exactly as yours with the abbas output stage. Do you mind posting pictures of your setup. I Would like to see how you connected the fifopi to the i2s2sim board.. also did you have to remove resistors on the d3 board so that the abbas iv stage can work?
How do you like the fifopi connected to i2s2sim compared to your previous setup? You mentioned you like the other setup compared to ians fifopi
Thank you
Tubo
Hello tubo, here is a picture...
Regarding resistors...yes with valve output you to remove them, r32 r33, iv resistors also..
The other setup is with i2soverusb viii and it is equaly good compared to ians fifo..
Yes, they are back in stock now. Hopefully my friend that ordered the parts for me gets them shipped before his, again hopefully, successful surgery.
Hi,
do you have any recomendations for an IV stage that does not use opamps ? I dont want to use tubes, so discrete IV on jfet basis would be a try, but sen and cen use the old toshiba bl transistors, that i cant source any more. Is there a newer discrete IV approach with parts, that can be bought today ? SMD would be nice, i can solder it and etch/cnc mill.

Hi,
The diyaudio store is offering matched sets of the lsk170. Not sure if they are as good as the toshibas but might be worth a try.
Linear Systems Matched JFETs – diyAudio Store
They have different parameters as far as i know. Is there no newer discrete iv design that i could use ? An SMD one would be very nice, or mixed (normal jfets and smd for resistors/caps). Does someone know of such an approach in the DIY community ?
Patrick published a BJT version of Cen I/V, with BC550/BC560 but as I've now noticed it's for 9018.
Another option is a D1 with mosfets, I'll find the schematic if you are interested

Dear ryanj
no need to polpulate Tr1,Tr2 ,C56-c59 ,R32-33,R35,R36 if we are used own output stage . Plam to use tube output .

It were nice if someone shared other schematics for tda1541a discrete iv...
I only can share that i built the ddnf iv and it sounds good. Just search on diyaudio, there is a thread about it..
Here is the link : D1 for TDA1541 thread (the schematic can be found there)
I've done a comparison for another DAC (ESS 9018 and 9028) between mosfet, BJT and Jfet stages and I prefer the mosfet one but they are close. It's apples and oranges so it's better as ryanj decided to have it without the output stage.

Works for me but anyway ZenMod posted an updated one (the original had a capacitor reversed) with voltages / currents, here it is. It's a general one, I haven't seen one specific for TDA1541 and some diyers stated that it works as it is.
