AudioSector-chip amp kits, dacs, chassis - Page 101

The best way to do it is to add another 5V regulator with 10-20uF cap (after regulator). The voltage to the regulator should be taken directly from +UD point ( on the schematic it's +side of C4) through additional ferrite.

BTW, did anything further happen about a new integrated amp chassis, mentioned a while ago in this thread?

When I was there a month ago, I was told that it shouldn't take more than two weeks to complete production run of a chassis. I was quite busy recently, so I did not inquire, but I will give them a call early next week.

What do you have on C3, C4, R1 and R2? (R3 is just for the Knome hat LED right?)

Yes, R3 is for LED. I'm not using C3, C4, R1 and R2, as I don't find snubbers appealing.

How do I go about ordering one of your DAC kits? Short of reading through 51 pages of threads to find the info. I see nothing about it on your website. thanks for the info!

The link to the info how to order DAC is posted on my website, in Latest News section from May 18th.

I prefer to keep a low profile on that product

Forgive me for offering a reply but...

It's patents. Despite how questionable their premise.

Many of these DIY projects emulate patented commercial designs, and one doesn't want to raise the ire of the manufacturers by appearing to be a large commercial threat.

Likely nothing more than a cease & desist would come of it, but who wants that?

that's why folks don't sell amps based on nelson pass designs, not why peter doesn't advertise his dac kits (which are definitely not of borrowed design).

In my case it's actually the opposite: my commercial design emulates DIY project. I still want to continue selling it as a kit, however, don't want to compete with commercial offering either. That's why it's not really advertised as a kit and sold only to those who make an effort to find it.
