Post some pics and a description.

I made 4 Felix's, here is the version using the CoilCraft P3717-A 27mH CMC and the Vishay F1778 X2 caps. The box is made from 1-1/2 Radio Shack 270-1805 6"x3"x2" plastic project enclosures. I cut the 2nd box on a band saw and joined the two together with screw pins and ABS plumbing glue resulting in a strong ghetto box. The exotic 14/3 wire, Leviton CR15 outlet, Leviton plug, in-line fuse holder and 3A slo-blow fuse was sourced from my local Ace Hardware.






The Felix allows low level detail like room depth now emerge from the background. Instruments now have more space around them and the living room's front wall disappears, cymbals shimmer and decay naturally. Digital music is smoother which means it can be played louder and vinyl is magical with instruments and vocals floating in space.

Details in the Lab Circle http://www.audiocircle.com/index.php?topic=25757.msg869560#msg869560, but here ya go - quad Felix

WGH, TomS - Very nice, straightforward builds. Its interesting that everyone posts pics that obscure where they've fused/breakered the filters with inductors rated for less than 15amps... 

EDIT: I need new glasses. Wayne has cleverly implemented his fuse with an in-line fuse holder.

Smoke 'em if you got 'em.

Where are the Felix PC Boards available?

[Sonny]

how does it sound with the Felix in the system???

I also built a number of Felix's in a Welborne Gatekeeper case that also had filtering.  As Wayne mentioned, it seems to lower the noise floor.








Occam, you'll notice separate fuses for each Felix. 

Thanks!

Looks very nice Tom...how muc was the project?  may I ask?  And this is just conditioning, no surge protection or anything, correct?  But then again, if the equipment was built well, there should be surge protection already. Right?

Thanks
T

Thanks Sonny!  I don't remember exactly how much the project cost as it was done a number of years ago but I ordered all of the parts through the Felix group buy.  The circuit board was nice to solder and align the parts but you can still build a more compact version by soldering the parts directly together, which people have done.

Barry, unfortunately, I don't think that the circuit boards are available any longer.

I have no surge protection in my system other than the fuses themselves.

That's a bummer, but thanks for the info Tom.

I know this may have been talked about before, but what about monster products such as a HTPS 7000 or so?  Would these be a good investment if bought used at say, 60% or 50% of retail?

Thanks

And it's even on the hot lead.

Barry, seems like it would be easy to build, I don't think you need the board.  My question is what size coils to use???

You can find all the help you need here: http://www.audiocircle.com/index.php?topic=25757.280

You don't have to use the Felix PCB although I do like it.     There are alternatives listed in that link that I provided.

Thanks for the direction Jason.

Here are pictures of my DIY balanced power unit in various versions over the past 6 1/2 years.  I am currently employing three transformers each feeding its own duplex outlet.  The large transformer is a 2kVA Equi=Tech Q type, and the two small ones are from Toroid Corporation of Maryland, 250VA each.  Outlets are Furutech FP15A silver and Oyaide R-1 (the pictures were taken before I swapped out one of the Furutechs for the Oyaide). The breaker is a Carlingswitch magnetic hydraulic.  All wiring is OCC copper and silver.  Power inlet is a Furutech FI-33 gold.  All terminations are silver and gold plated copper.  All hardware is non-ferrous.  Auricaps are across primaries and outlets.  I've used acoustic damping material on the inside panels and top cover.

I use Littelfuse iTMOvs for surge protection.  These have an integrated thermal element that prevents them from flaming up from catastrophic overload.  They have a third lead that can be wired to a monitoring circuit ranging from as simple as an LED and dropping resistor, to a circuit that cuts off power when surge protection is lost.  I use the front panel LED as the indicator that surge protection is intact.

In my first version, the large transformer was a Torioid Corp 2kVA unit, but I found it too susceptible to power line DC offset.  I also initially used EMI/RFI block filters and dead-front GFCIs, but found that to my ears, they contributed to a haze over the treble and midrange when in the electical path.  I ended up eliminating them in later versions, after extensive listening with them in circuit and bypassed.  All parts were selected as the best possible I could obtain without regard to cost, along with listening and tweaking.

Benefits are a further reduction of an already very low main system noise floor to vanishing levels.  I've also found there are notable improvements in detail and transparency, and sense of increased weight and extension in the low frequencies.
