building a powersupply by my self

Is it posible to build a powersupply by your self?
Does anybody have some info to make it?
NAIM: NAIT5,CD5i, Interlink

Dangerous question here. Visit Pink Fish Forums and choose the DIY forum.
I am sure you realise but you will invalidate the warranty if you use anything other than a Naim powersupply to drive your Naim kit. It's your risk.

Yes it is possible to build a power supply by yourself.
It is possible to take a loaded shotgun and point it at your Naim system and pull the trigger.
Doing both will have a similar effect on the sound of the system.

Of course you can, I've done it myself with an old 42/110 combination. I'm a "seasoned" electrical engineer and have worked in power electronics among other things.
I currently use a REAL HiCap with my 102, I have no interest in something going wrong and blowing up my nice kit.
If you have little or no experience with electronics I would recommend not attempting it for use with your Naim kit.
And, of course, Naim recommend against it, in the best interest of your safety and the best possible sound.

Yes, it is possible, there are designs around, people build them and they work.
The likelihood of it blowing up your kit is very low, if you build it correctly, as it will be based around a transformer that steps down the voltage, so mains will not be presented at the output side.
You would also test the output before putting it anywhere near your lovely Naim kit.
However, building anything like that does require some electrical knowledge, and some soldering ability.
If you've got neither then you may well make a mistake and it won't work.
Incidentally, I would think that the risk of damaging yourself would be much higher than the risk of it damaging the Naim kit.

I built one a few years ago, very carefully (I'm an EE with >20years). Very pleased with myself - sounded great and my Fluke DMM registered barely a flickering digit of noise on the most sensitive AC uV scale. Then I got a real Hicap and it sounded in a different league and the same DMM registered a solid zero uV. Go figure. Respect.

I built one, rather good and not a little complex. I use it with my 252.
It's a SuperCap and seems to work rather well.

...But then Adam was under pressure at the time.
It was part of the entrance exam to stay working at Naim

This thread has a whiff of nepotism/self adulation about it.
With all due respect to Naim there are other power supplies out there, some DIY and some off the shelf. Most are a lot cheaper than Naim and the one I use sounds infinitely better than the Flatcap and then Hi-cap which preceded it.
Whilst I usually sit quietly and read the forum without contributing I do think that some of you guys are a bit blinkered to say the least.

I'd like to build one of those too.
Can I use the same facilities that you did?

But then you don't have a Naim system anymore do you? You have something else.

Am I now meant to cry?? Are only Naim components allowed?? As my daughter would say 'you need to get out more!'

Of course they are - but then they prove my assertion right don't they?
You don't have a Naim system, you have something else.
Oh, you can cry if you want to. It's your party.

Hey Joe,
What other asinine comment can you come up with? You obviously live in some sort of fantasy world where only Naim engineers live and every other EE is incompetent.
Delusional hallucinations can be quite dangerous. Maybe you should check yourself into the local psych. ward.

Hmmm. I've seen folk building their own. usually results in "Rah rah rah mines better", "rah rah rah, mines cheaper too".... then often they sell off all their Naim kit. Curious - could it be the self-build wasn't actually better? Then the kit was sold after the loss of musical enjoyment (introducing a poor-cousin PSU)? Very few listen to the differences and are big enough to admit it - hats off to JeremyB.

Personally I enjoy the Born Again™ part when they return home tail-tucked because the hip-ness wore off or their New Guru upgrades to something even crappier;-)

"You obviously live in some sort of fantasy world where only Naim engineers live and every other EE is incompetent."
Do I? That's a bit asinine.
I never said anything of the sort. I'm stating that Naim engineers know best when it comes to Naim equipment.
Porsche engineers know a lot more about making Porsches than Ferrari's engineers do, and vice versa.
Is that therefore really such an inflammatory and ridiculous statement to make??

Whatever.

Well, you can count me out of the tucked tail and sold-off Naim crowd.
I did all kinds of weird experiments on my 42 including battery power of my home-brew HiCap, powering my 110 with a home-brew regulated supply (now that was a SERIOUS improvement!). My 110 still bears the scars of the power supply terminals brought to the outside after drilling holes, etc. I knew I’d never sell it and I never will.
None of this was to try to beat Naim at their game. Part of it was the desire to update my equipment on the cheap all the while learning more subtitles of design and construction along the way. Pride in accomplishment is the better half of this motivation. I must say that I’ve learned much from some amateur Naim forensics. And that knowledge will never be used against them; I don’t compete in the home HiFi field.
Face it, the HiCap "design" is straight out of the National Semiconductor data book. I can give you the page if you like. That part doesn't take renowned experts to conjure.
The magic is in the component selection and careful construction, and my hat is off to them for coming upon the combination (however that was) that makes these simple, popcorn parts sound so good. These are not high precision or hardened designs or military grade parts or construction but well-executed consumer electronics. Hell, the best executed that I've ever seen in consumer audio electronics. (I'm talking about my experiences with the 42 and 110 here, with peeks into the 250 and 102, none of the new stuff, so I don't know what they've done lately.)
Yes, I've toyed with the thought of a home brew SuperCap and may go there someday. Its "design" is also straightforward, but they've taken incredible pains to get everything right. I've got too many irons in the fire to take that one on right now, nor would I expect my final version to be indistinguishable from the sound of a real Super.
And you won’t find me mucking about in my 250, my precious Briks are on the other end.
A die-hard Naim fan here for sure.
