Capacitors quality for NON-OS dac with TDA1541

[jean-paul]

John ( dhaen ),

I will ask if there is a way of guaranteed continuing supply and what quantities you have to order, OK ?
What are you planning to build with this chip, separate DAC or mods of cdplayers ?

Jean-Paul,

This is not for DIY, so has no place on the forum. Would it be possible for you to contact me privately via e-mail?

Cheers,

To mush transformers ?

I started off with 1 TDA1541 S1, then added another one and it made quite a big difference more detail all over.

Each dac has it's own decoupling caps and LM317/LM337 regulators.

My goal is 4 in parallel.

Splitting up supplies to separate transformers also gives a nice improvement.

Currently I'm using 4 transformers and my goal is 7

2 for the CS8412 (2 X +5v)
2 for the TDA1541 (+5v, -5v and -15v)
1 for the Kwak reclocker (+5v)
2 for the output stage and I/V converter (+15, -15)

Hello,
i must ask, whay are so mush transformers good: 2 pieces for one power cascade. Do you have shure that this is more good if one transformer.
For my project i am calculated with 3 transformers: one for digital ( 2x2x5V ); one for analog ( 15 V )and one ( with two separate secondary outputs: 2 x ...V for tube anode voltage + 2 x heating )

What do you mean about my plans...

Hi Hifiwolf,

Happy new year to you too ! I am curious how your opinion is about the TDA1541-S1. Please let us know about the results and show us some pics too ( if you have a digital camera ).

Good luck with building your DAC,

Jean-Paul
