I am looking at this dac:
http://www.ndh.net/home/kboehm/T-DAC-P2.htm
the author says that the values of the filter section is calculated for usage without the 1:15 transformer.
If i would like to use the transformers and 75mH inductors what values is it that i should change?
the schematics can be found here:

I'm not sure about this, but:
with the transformer (depending on its bandwidth), you could even use no filter

Thorsten has a nice tube analog stage for TDA 1541 on his website... http://www.fortunecity.com/rivendell/xentar/1179/theory/vasfda/vasfda.html

thank you for your repyls.
Im sitting on a bunch of telefunken &siemens e810f. Also i already got the 4 inductors and the tm3 that is the reason im looking at this specific design.
Anyone who can confirm bricolo?🙂

Klaus's DAC is based on Thorsten's Adagio design.
I think Klaus still has a vistors book. If you leave your question in there, maybe he'll get back to you.

Hi Kasra,
Klaus did get back to me after a week or so.... That was back in summer. (N. Hemisphere 😉 )
I'm not sure that I understand your question exactly. I'm shortly going to be building Thorsten's Adagio
That uses the 1:1.15 transformers. You can see the filter values on his circuit.

dhaen.
basically I am building a dac according to the schematics further up.
Klaus says on his site that the values on the schematics are adjusted for usage without the amplimo 1:15.
Since im going to use the 1:15 and the 75mH inductors. i need to know what components that should be changed in valueso i can use the transformer.
Anyone who even built this one?`

I'm building something similar, but with two TDA1541. Look at an earlier post 2*TDA1541.
I am using the TM3, but i don't have any additional filtering (yet?).
Can't say i hear a difference when i compare with a normal player (freq response that is, not overall performance!).
But the filtering is probably more for keeping high freq away from the next stage and not so much filtering in the audible range (?)
Going to do a proper listening tonight with a friend and a well known set. See you the DAC performs.

Isnt there anybody who atleast could guide, which parts that need to change value in order to use the transformer?🙁
