Hi guys,

The best way to contact me is to pm, so sorry I let you guys waiting. I just wrote you, so if you still are interested in some boards, just let me know.

I really like the HFE diodes, but because the guys are getting hot to above 90C° when delivering 3A, I recommend good quality Vishay MBR1045 instead, which have nearly half Vf and got comfortable warm. I always let it people know within the HowTo, but want to make the hint "official" here.

I you have questions, let me know.

There are people around the world using the LT3045 boards, I'd be happy about people sharing their experiences here, so feel free

Regards

Stammheim

Hi @Stammheim!

I tried the first of my two single ps boards today. Here is my initial impressions I just posted in my CA thread.

The true experimental tweak thread - Page 150 - Networking, Networked Audio, and Streaming - Computer Audiophile

Thanks a lot for a brilliant product!

Best regards,
Micael

Hi Stammheim! You asked me some time ago to post about my project. Here is what I did with the superb PSU. I love the look of the blue heat sinks which are visible through the venting openings on the top!

More information in the DAC thread: Dual mono AK4495S with AK4137 and MCU/LCD DAC kit for $160 and more photos on my website.

Very nice build @aakkonen! I will get my single ps's boxes later on and surely want something that shows the beauty of Stammheim's boards. I love when beauty in looks meets beauty in SQ.

Hello
I am new to this forum.
Do you have more naked boards available?
And if so, what is shipping cost to Belgium?
Greetings

Installed the 6 x LT3045 Power supply in my audio PC last week.

Audio PC - Gigabyte H97M-D3H & PPA OCXO Mobo, Intel Core i7 4770S • 1150 Haswell, Crucial Ballistix Sport 16GB Kit (8GBx2) UDIMM Memory Modules BLS2K8G3D1609ES2LX0 DDR3 PC3-12800 • 9-9-9-24 • set at 5-5-5-20 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V • 1024Meg x 64 • Low Profile, Bios set 800mhz Cpu & Memory, Teradak ATX Linear for 20 pin ATX on Mobo, Paul Hynes SR7EHD 12v for Mobo, 5v for clock.

It has provided a great step up in the sound, better bass attack cleaner transients.

Got the boards built with both channels combined to power the Motherboard RAM at 1.3 volts.
Startup amps for RAM are at 2.9 amps and quickly settles at 2.7 amps.

When I first set it up i supplied 5v in from a Paul Hynes power supply and the heatsink was getting too hot so switched to 3.3v in off 2 x Lipo4 batteries trickle charged off a 3.3v linear supply and now running at a nice temperature.

Really impressed with this Power Supply so ordered a second unit.

Nice!

Here is another thing you might want to try out when you get your second single ps?

IMG_6984.JPG.4b24e2e637ff93d9eb141074a699047e.JPG

I have tried it out using a Gophert csp-3205II (floating lab SMPS) powering my Brooklyn DAC with awesome results in terms of SQ.

Three power supplies in series is surely over the top. However, the SQ jump is unquestionable in my setup and it could hopefully give you or anyone else food for thoughts!

Forgive the noob questions... but is it no problem to feed the second ps a dc voltage? (apparently not).
How do you set the voltage of the "first" and second PS if for example 12Vdc is the final output?
What happens to the max load in Ampere when put in series?
