Pictures of another TDA1543 coverter

Lucas,
when you’re not using the regulation on the DDDAC board, you should only solder in the BG caps. AFAIK you would have to increase the voltage of the external supplies to feed the regulators on the DDDAC board. If this would result in better performance? I don’t know… Maybe then you could just as well go with Doede’s original Accu supply.
My trafos are 12V AC (16VA) for the 8.5V regulation and 8V AC (8VA) for the 5V reg. I think that’s adequate.

Hi Bartek
I don’t have a full scheme of this DAC. I just made sketches from the single boards. I will upload some of them during the next days. So check the link in the first post from time to time.
But here are already several full schematitcs available.
This DAC is based on:

Highly filtered and regulated power supplies.

Yes, it’s the PS suggested by Elso.

Elso,

As you already know I actually do not agree with your I/V approach (though I can understand your reasons), but for this -

Listening test conditions???
I live a while with the mod and if I like it I keep it in.
If I don't like it it goes out.

- you are my hero!
