Below is an old thread of Jim Hagerman’s Mains Power Line conditioner and a PDF file I recently found.
I think Jim’s thread / conditioner project is worth re-opening. Most of the parts in the original BOM are now obsolete.
A new BOM and semantic for Jim’s conditioner would be fantastic.
If anyone out there has built this conditioner or may have additional info please chime in.     

I'm not sure, but it look's like Jim is no longer on AC. I don't know why.

See here for why: http://www.stereophile.com/content/industry-profile-jim-hagerman-hagerman-audio-labs#RsbXji30FQwzmpfb.97

FWIW, I polled several kit designers & manufacturers who are in the biz...they do not share his views with regards to supporting clientele who desire kits. But there are plenty who do share his philosophy as well.

The ones who don't share Jim's views actively and earnestly seeked out the support of advanced diy hobbyists who had the requisite skills of debugging (and were pretty good about not selling to neophytes). Unfortunately I believe that Jim did not do so.

That being said Jim is a very talented and smart engineer who certainly has the chops to design excellent sounding audio gear.

If you want to use an inexpensive mains power line conditioner that is competently designed, an alternative might be Paul Kaplan's Felix (low currents preferred like 3A). There are plenty of threads for you to search. You can also look into the Felicia conditioner and JoshK wrote plenty on that as well.

And of course there are loads of threads on Balanced power conditioning, etc...which was first popularized by Transcendent Sound, BPT, etc...

Anand. Thanks so much for all this great info. I'm looking into 3 projects at the moment. This info will help me greatly.
If anyone has built the Hagerman DIY Mains Power Line conditioner please chime in.

[WireNut]

Anand. My question is. Since Jim's BOM is obsolete what would the current issue component numbers to purchase be ?
I'm researching it, but my knowledge is not equal to your's.

Wirenut,

I don't know if it was obvious in my post but the Hagerman design is fairly generic and the design of  the Felix will most likely provide you with a better performing filter as Paul Kaplan has adjusted/tweaked the values for superior common mode noise attenuation, etc...

I personally don't see a reason to build the Hagerman unit which uses off the shelf modules when the Felix and Felicia are available. Measurements and such should be available when digging through the archival links above to see how well the Felix and Felicia perform.

I would build either a Felix specifically for each audio component you desire or have one box with several Felix filters. Examples of such are in the links above. If you want to experiment with balanced power filtration, then the Felicia is an option.  Commercial examples include Transcendent, BPT,etc...the Transcendent is available DIY and prebuilt along with the BPT which is prebuilt.

If this is in over your head, I suggest you start off slow and reread the above links.

That being said, if you insist on building Hagerman's conditioner, the power line filter module (for various currents) are available here:

Everything else in the Hagerman design is pretty generic/off the shelf so to speak.

Best,
Anand.

For the most part, the Hagerman unit is just a box for legitimate, designed for this purpose and safety tested filters.
The filter manufacture has measurement documentation as to what it does.

 Hi Anand and speedskater.
I'm reading about the Felix now. I also looked at the transcendent conditioner. Mouser no longer has the Kobiconns, I believe they are now obsolete.
I'd go with a different manufacture if I built the Hagerman. I like the idea of several Felix's in one box.
I'm holding off building a conditioner until I finish the treads.
Thanks for all the info.

Steve.

If you are going to build several Felix's (I'm not saying that you should) then place each in it's own box with as short an output cord as possible. Attached to the hi-fi component's chassis is best.
