Default Thorsten's Valve Output Stage with TDA1541DAC

Has anyone tried Thorsten's circuit for a valve ouput stage with the TDA1541 dac?

I'm interested how this worked generally and also whether anyone has used the TDA1541 in nos mode with this output stage.
Many thanks
David

I have built it some time ago thinking to use it in my next DAC but so far I haven't assembled the DAC yet.... first I have to complete the MOX x-over... a tube preamp and to properly settle in my new house

Cheers

If you can post some links for these updates it could be very useful....

Cheers

That's the problem, it is text spread out in several forums and I don't have that collected. That's why I was asking in the first place, in case it did exist in one place updated.

sorry

Konnichiwa,

Okay, quick & painless.

I have published a few circuits.

1) The one from the Valve Article - also linked in post #4 which is actually not a circuit as such but a blueprint meant to be adapted by the individual builder.

2) The one I used in the final accounting with my "Adagio" TDA1541 DAC:

http://www.fortunecity.com/rivendell...io/Adagio.html

3) The one specifically aimed at the TDA1545 (and no other) which has been ripped off all over the net without propper attribution to me (which really pi...es me off) for example here:

http://www.ptsoundlab.com/secnumeriq...tagelampes.htm

(The siteowner also copied several other of my schematics - not even having the decency to re-draw them - again completely without attribution!!!)

The design originated in a "lets hotrod the Philips CD723" Discussion on a German board.

A "non-oversampling" digression was discussed here, this might be a neat upgrade for Yeo's TDA1545 DAC Board....

http://db.audioasylum.com/cgi/m.mpl?...tweaks&n=52708

4) The "latest" TDA1541 Analogue stage as here:

Click the image to open in full size.

There have also been some discussions on circuits for the TDA1543, but they are posted in my Yahoo Group and thus not directly accessible....

I hope this helps.

Hiya,
Thanks for the reply. The 'latest' tda 1541 circuit you post below, is that sonically better or similar but with a much lower component count?
Thanks
David
