I was wondering if someone has done a 1ET9040 build and could share some details? I only have the Micro audio Cobra S1 SMPS set, the 1ET9040 and a pair of the new Neurochrome buffers. That means I will need to source the cabling, switches and enclosures, anyone seen or has an idea where to look? Will be truly appreciated!
Sounds like a fun project. Thank you for your support.
The documentation for the buffer is now online: https://neurochrome.com/products/universal-purifi-input-buffer
I give the part numbers for the power connector in the design doc. I assume the Micro Audio uses the same 6-pin connector as the Purifi. If not, I suggest tossing Sami an email.
The 20-pin ribbon cable can be DIYed or bought from a distributor like Digikey. The connectors are IDC connectors with 2.54 mm (0.1") pin pitch. Something like Assmann H3AAH-2006G would work. Search for the part number on Digikey.com and you shall find.

Dear Tom,
You have no idea how grateful I am to have you, there are very few people who are dedicated as you are, so helpful, so knowledgeable. Thank you from all my heart, makes such a difference in this crazy greedy world...

I would also like to join this thread. My plan is to build four 9040 EVAL4 mono blocks using the Hypex SMPS1200A180. Case choice is the recently heavily discounted mono case from diyclassd. Like the op the biggest obstacle is obtaining the correct wiring harnesses. Ghent only offers their harness kits with the purcase of the eval4 enclosure such is extremely expensive at this time.
That is a great case! I wish the Micro Audio SMPS could fit in there... I had to buy a bigger enclosure and I went for a pair of these:
I will have problems attaching the boards and make two compartments(SMPS on the bottom then in the middle I will use a steel plate for the other two boards) and then rout all the cables, the wall thickness is 8mm and drilling the back for IEC, binding posts and XLRs will be fun 🙁
I was considering buying two of the diyclassd cases and separate the SMPS and the amp/buffer board and stack them but it will not fit for just 5mm...
Working on a cable solution, if I find a source I will let you know, please do as well.

Not really happy with the enclosure. Not all holes fit with openings(at least 1mm off sometimes), scratches here and there, cheap becomes expensive. And it wasn’t cheap…
