You’re welcome.
Thus : I could not stand for wait for your answer, so I tried it. 1 capacitor b4 & after the Drok.
Result : dead good !
In audio source PS issued, the noise is critical and can be heard easily with harsh & hard sound.
By adding just a tiny & cheap capacitor, b4 & after this Drok, the result is a pretty good PS, and pretty “clean” because the sound has improved by a large margin.
I made a feedback in this post in a French forum : http://enceintesetmusiques.com/forum/viewtopic.php?f=36&t=1805&p=93742#p93527
I’ll follow your point, I will add a 2nd capacitor after the Drok, to see if it sounds even better than with only one.
The benefits of this Drok :
– not noisy. Maybe because it uses switch franquency at 300kHz.. Any idea about it ?
– compact. So can be integred into a nice box after testing session
– no heat ! Thus, basic box with “standard” opening will be enough. We don’t have the drawbacks of standard regulators that put the tension diff into heat, thus require big heat sinks.
Very nice so far.
So, I bought another item for testing upon another digital audio source.
And I plan to buy 4 of this same Drok for testing (same PS design) to power the digital part of my pair of full digital amplfiers.
When something is efficient, reliable & not expensive : I just copy/paste 🙂 and put it everywhere I can 🙂
