Hi Jim,

I was looking into building your AC line conditioner but find the line filters you specify are listed as obsolete in Digi-key.   It seems that Qualtek are the new manufacturer that is carried.   Can you spec a alternate line filter?

Thanks.

I suppose this was bound to happen.  You don't have to use my design.  Just buy whatever you think will be appropriate.  All of these filters are good.  Pick one for the input that already has the power cord connector built-in.  The others, merely depends on how you feel like wiring.  I had originally chosen filters that had terminals.  That way I could wire up various configurations. 

Also, the Lansing is not the best chassis for this.  Fit is way to tight.  Find something easier to work with.  Maybe with the outlets on top, things fit better.  You can still use the article for basic conceptual layout and wiring.  It purposely separated outlets between power amp side and preamp side.  I don't know if it really helped a lot, but makes sense to me.

Digi-Key??  I just built mine a few months ago and purchased all the parts from Mouser, as specified by JH in his original design.  I wound up building a wooden case, substantially larger than the Lansing box.  It was a very nice project.

Hi

I misspoke, miswrote?   I meant Mouser - the current online catalog shows them as obsolete and not in stock.    Did you experience a sonic benefit?  You built the bugle as well, right?

Thanks.

where is the DIY line conditioner?  I have never seen or heard about it.  Please link.

It is under the technical articles section of the Hagerman Tech main website.

Sonic benefits?   Well, that's a tough one for the Line Filter.  My understanding of this is that each particular electrical installation/system would benefit to a greater or lesser degree based on many variables.  My electrical feed comes from a dedicated sub-panel that just does my "sound and pool room".   There are no motors or other "noisy" things being  supplied by this.  I think this helps a lot.  I built it primarily for convenience and looks, then filtration benefits.  I have built 6 JH products, Bugle, Cornet2, Clarinet, Ripper, UFO and Line Filter.  The Line Filter only cost something like $35 plus case.  I am not gonna test it out by dragging all my gear into the kitchen and plugging it in to the "refrigerator, DW, GD and fluorescent haven".  The engineers that design these devices probably have some "visual scope" mechanism to measure the filtering.  I don't, the Line Filter is cheap, recommended by JH, and is very convenient for plugging things in.
