Start mounting the power supply ...
All components are purchased from Farnell, not enter Chinese component in my project.
I decided by Epcos capacitors, are reliable, and amazing quality.
Connectors are male and female, reliable, safe ... comfortable and tidy.

Come the resistance from the voltage regulators.
The best quality you can get Vishay Dale 1% directly from Farnell. I like the blue color

An externally hosted image should be here but it was not working when we last tested it.
Voltage regulators assemble, with Kapton spacer no need thermal paste to improve thermal transfer.
Important: If you assemble Chinese sinks, not assemble Kapton spacer ... the bad finish not is good for kapton.

Capacitors come from Germany. First fixed with self adhesive, and then welded. Perfect size, excellent quality and performance.
We continue with the input signal circuit… Yes is a Tentlabs oscillator low jitter, no chinese quality here
We continued riding the circuit oversampling ... we mounted the master clock, to install the SAA7220. NOS mode not is for my ears, fatigue my mind.
The SAA7220 is from a Marantz CD player CD-65 MKII, and the TDA1541A decoupling capacitors are selected EPCOS 100 nf ... I bought 80 units and selected exact values.
NXP is a Philips made component.

One problem ...
The oscillation frequency from the clock tentlabs not is correct, we correct it with the adjustment terminal…

We continue with the output circuit ... Naturally Vishay Dale 1% resistor from Farnell. Chinese components banished from my circuit.
An important consideration. Never install a chip TDA1541A if you are unsure of its origin.
I do not trust Chinese suppliers ... too many chips have the same week and year of manufacture. It's too risky.
It is much better to buy an old Philips CD player for little money and remove the TDA1541A.
Certainly never would spend a single euro on a TDA1541A S1 or S2 of Chinese origin.
Your project will be as good as the worst of the components you mount

I have a reel intersest in the Passive CCDA preamplifier
would it be possible to gett the power supply
for the above project

Hi
Nice to see/read your own threads after a couple of years. I was good :-D, wasn't I ?
I'm here again and I'm back but maybe not in the same shape as of 2010 ;-)
I have work cleansing my cellar and decide what projects to work on. Other things in life.... also,
See you all DIY guys. 🙂
