Hi,
I have two bare pcb boards for the Audio Crafters Guild "Super
Symmetric Power Supply" that I puchased from Norm a year or two
ago.....I cant seem to find documentation(schematics, parts list,
etc..). I believe its a stable power supply for his XDAC.
I need to start buiding it for a dac project. All contact info for
Audio Crafters Guild via the web is stale or down.
If anyone has any info on the "Super Symmetric Power Supply " or how
to contact Norm Tracy please email me at trq10180@flash.net or
tquinn@redback.com.
Thanks!!!

Darn, the ACG site does seem to be down. I really liked that site.. and the SSPS was a nice little design. Well, i seem to recall having downloaded the SSPS info (schem, pcb layout and BOM) at some point only I can't seem to find it right now. I could have it at the office... if I find it, I'll let you know.
The ACG site is down, but try:

I read about that site in the paper (www.archive.org) which keeps snapshots of the internet - but hadn't actually had a reason to use it until now.
Could be quite useful from time to time.

Here's my copy of the SSPS schematic, for posterity.
An externally hosted image should be here but it was not working when we last tested it.
FWIW,
I had an email from Norm Tracey yesterday; SSPS boards are still available. Looks like he will soon surface from some intensive R&D with a new SACD and DAC!

Hi fmak,
One of the reasons I contacted Norman was to order a pair of SSPS; I'll let you know how they sound!
The chokes are 'CMC's or common mode chokes designed to block out capacitivily coupled noise that makes it through the transformer. They are often used in digital work where their high leakage inductance filters out RF noise... the result will be quieter backgrounds, better detail and definition.

Another power supply kit
This one is at http://www.welbornelabs.com/ps1.htm. The Linear Technology LT1085CT/LT1033CT are the best three terminal regulators that I know of.

PCBLR is trace on printed circuit board.

large gifs`?
Hi jwb,
how did you get to post that gif image? I tried to post a scan the file of which was only 20 k in size, but the forum computer refused to accept bitmap images larger than 800x600. How come it accepted yours?

Theory apart, not necessarilly sonically better. My own experience points to low noise, low source impedance as prerequisites. Inductances and resistances do not help; they seem to suppress dynamics. Pl post your assessment.
