Hi Bricolo,
I'm not very keen on using veroboard for proto's especially
high speed stuff like unfiltered PCM.
I usually just start with a solid copper covered PCB and
neatly xmas tree everything on top. Depending on circuit,
a double sided solid copper covered PCB with PS rails cut
into one side with a dremel or hacksaw also works well.
With this method you get a good low Z ground to decouple to.
I also find it quicker than vero.
YMMV.
Cheers,
Terry

Do you mean point to point, with the components glued on a copper plate?
BTW, maybe we don't have the same idea about what a veroboard is. I'm not sure I'm using the right name, I'm talking about the prototype board with the pads around the holes, not the one with the stripes.
I was planing to use a double side one, with a ground plane on the components side.
Hi guys!
Mr Broer,
I have few questions..... I have tda1543 and cs8412 based dac without reclocking and with passive i/v conversion. It is running at 7V power supply.
I am reconsidering to try some things at the output of the dac. Maybe this circuit would do the thing fine?
first:
If I get this right the resistor form pin 7 to ground is 1k2 if the power supply of the tda1543 is +5V.
second:
What type did U use for the diode in power supply regulator near ZTX690B and which type is Q4?
third:
Pot 1k is a potentiometer (near RSOA1A 56R) right? Could U tell me please how to adjust it (adjustement procedure like Jean-Paul asked in post #30- or at least where could it be found (Iknow how to use Search engine but don't now what to look for
).
Fourth:
Is this much better than using passive i/v?
(Peter Daniel - what do U say- do U use it right now?).
thanks
daniel

12.7V version for 1543/3 ?
I worked out this version for my 1545 that I think will work for 1543 aswell.
I wanted something that will run from a 12 volt battery
As I need a cap on the o/p anyway to protect my transformer volume control from even the tiniest amount amount of DC I just settled on a big offset at the output.
It measures very well in simulation.
What do the experts think ?
does it pass ?
any drawbacks ?
