Thanks for the clarification steen. I just picked this thread up, read through, it was tough at times to follow (still a newbie). Now its all good, thanks.

Toole regulator / NS10 PCB GB
Hello,
Steen has started a GB thread.
http://www.diyaudio.com/forums/showthread.php?s=&threadid=134387
May I suggest that we continue GB discussions there?
Cheers,
Dennis

Some newbie did messed up the GB List - please guys check your orders.....my name and my ordered pcb are deleted and some other values are changed.

That usually happens when there are no more vacant lines and a newb is trying to order. Not everyone can find those pesky || lines. Nevertheless, it is pretty annoying.
@ 360 reg-boards now, not bad at all.
🙂
Wait for the new PCB price - I think people will increase their orders. I am planning to double if the price will drop under 5 Dollar.

Heck, simulating circuits while listening to some music on my new Piezo headphones, which happen to be older than I am, is much more fun than writing a Comparative Justice term paper. Thus, I present a 5v version of the toolereg, sized for a 50mA load.
I have not really looked at using reference diodes, but no real reason not to. It would give us a bit of consistency, as the current versions will need to have their voltage trimmed in, especially the LED ones. My LED model has a 1.7v forward voltage, and I have seen ones anywhere from 1.5v-2.1v, though consistency between LEDs of the same model is quite a bit better than that. So, all that said, want me to take a look at using a vref IC for these LV regs?
What they hey, lets kick it up to 410 boards for this group buy. I bet you didnt know what you were getting yourself into when you volunteered for this, eh Dennis? I have run a big PCB group buy before, it isnt much fun.

Caveat venditor, baby! I needed the 3.3v and 5v supplies for myself actually, gonna eventually do a DAC based around them, and the +/-12v regs. I might need a -5v reg too, depends if I go with the PCM1704 or AD1862.

Sheesh Colin, you sent me googling... LOL 😀
Are we making a GB an that one also?
Re: Re: Re: Re: Re: Re: Re: Good News, NS10 group buy
Not really, I was just curious if you had made the sims on those ref's.
You better get that Law-paper done instead😉
🙂
We forgot to sing the Birthday song for Tony😀 A late Happy Birthday, Tony

Thank you guys for the nice wishes
BTW, I have added an important post on the Tooleregs @ the GB thread.

Wait, what? Man, you guys are full of surprises. Trying to control dissipation on the shunt reg input CCS? Dont pre-regulate too close, it works actually a bit better with more voltage drop across the CCS. Of course, that is ripple rejection, and especially with a CLC filter AND a prereg, that really wont be an issue, eh?Manu said:
Oh yeah, sorry I forgot Tony: feliz cumpleaños, mi amigo.

'Evening Manu,
If you are going to expand you "raw" supply into a full regulator, could you add a snubber R-C network next to the inductor across the first capacitor C101 - 1/4 w about 470R and MKC about 4nF and if you have some more room left, add another 10nF across both of these - gets rid of diode ringing that is still present even with the u.fast diodes.
If any more room at output (!) add a Carlos snubber there, too to get rid of the LM3xx device noise.
Then, to top it right off, add a second TO220 and incorporate a Gyrator like the Teddy-Reg and we'll call it the Manic-"Raw"Reg! (just kidding!)
Articles about snubbers can be found at TAA 3/94 (yeah, back then!) by Scott Morovich - and follow up discussisn by Jim hagerman TAA 7/95) and much more since. Snubbers DO makes a big difference to the sound for just 2 (or 3) components when you get it right.
Can also fit a Solen PP to the shunt-Reg board (easy available in Eu) altho have found the Jentzens to sound better than either the Rifa, Wima or Solens, but they all do work okay.
