Discovering I may have the cleanest AC power in USA

PS Audio Noise Harvesters are on sale. $50 each.. So naturally I had to buy a pair. 36 hours later in my home.Well I clean the prongs, Caig Gold them, and plug them in.
Nothing.
Nothing.
I am wondering broken? DOA?
I move them to other outlets not on my stereo in the kitchen, in the bathroom (the bathroom has a air cleaner plugged in the same outlet, motor running). OK a single blink.
I remember the dimmer thing. Plug the Noise Harvesters into the stereo again.. and turn on the only dimmer in the place (in the bedroom, on a different circuit) KABLAM!!! Now they are blinking pretty regular. OK they are NOT broken.They also blink when I put them on an Adcom AC box also on different circuit than stereo. Both the Cable internet box and the WiFi box are on it. And yes they blink every minute or so.I checked the Furman REF 20 outlets, no blink. The direct to the amp.. no blink.+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
So I apparently have just naturally the cleanest AC line in America? (For my stereo equipment.)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Part of it may be the fact I packed the duplex enclosure 20 amp single line I use for the stereo with small quartz crystals coated with Automotive dielectric grease, in small baggies, the duplex is also the Furutech GTX NCF type, and the wall plugs are also filled with the loose small quartz crystals, plus some flattened baggies of the crystals wrapped around the outside shell of the plugs at the wall
Good thing I only ordered two of the Noise Harvesters. More are not needed. (and I actually do not even need the two. but that is OK. I can keep them as a sentinel, to know if I ever get noise on the lines.
So I do not know if my home made anti noise crystals work magic? (along with the Furutech NCF which is basically a refined version of my own crystals) or if I really do have some of the cleanest AC around. (PS I live in a 90 unit apartment building, folks above below, around me. Things like my frig I have several ferrite cores with the AC zipcord wire wrapped in and around them, ditto air cleaners, lamps..

I got two of those harvesters, also.  My HT/2ch is in the living room on a shared 20A circuit.  When I plugged 1 into the shared wall circuit, it blinked a little and then went out,  When I plug the other one into the front outlet of my Furman Elite 20-PFI, it blinks constantly.  It will stop if I turn my power amps off.  The other one  still doesn't blink either way.  I did switch the harvesters to make sure they were both working.  Most of my components are plugged into the back of the Furman that is plugged into the same shared line.  I really can't say I notice a difference in the sound quality either way.

Anyone have an explanation as to what might be going on?

If the Harvester stops blinking when you turn something off. Clearly that particular something is spewing HF junk into the line. I am going on the possible unmentioned ?fact? that the amps are plugged into the Furman? IF the amps are plugged into the wall.. Then yeah it is a mystery.              
If the amps are plugged into the wall, and not the Furman. Try unplugging everything else going into the Furman .. except the amps left on. Does the (still also plugged in and turned on) Furman Harvester still blink?         
Another crazy wild guess is the amps are sucking up whatever is on the line?? and when turned off that HF junk is free to wander.      
(if the amps use a digital switching power supply those do make HF noise)

I had a similar experience one time when I moved. The little doodads made a significant difference in one home but had zero effect in the next. I believe it is very telling that the new place was a much newer building than the last...

I am one of those so-called ’audiophiles’ who believes in the power of ’clean juice’. Fact is I got a steal on a ESP The Essence power strip because the seller had just paid big bucks to have the power company install a distribution transformer in front of his house and no longer benefited form the ESP.

Since I use the front Furman outlet to connect my TT motor when in use, I had moved the harvesters to other shared wall outlets and very rarely.saw them blink.  After seeing your post, I tried moving them back.  My SS class A/B amps are plugged into the back of the Furman along with most of my other A/V equipment.  I recently moved another similar SS amp I use for surrounds and plugged it directly into the wall, same shared circuit.  Now when everything is on, the harvester blinks bright like a constant strobe while the one in the wall doesn't light.  Now when everything is shut down, the Furman front one still blinks a little and the one in the wall is still dark.
My conclusion is that the Furman surge and noise suppressor is adding noise at least to it's front outlet, but not to the wall line.  The next time I have my rack out I will try plugging one of the harvesters into the back of the Furman to see what happens.  My power amp manufacture suggest plugging them all directly into the wall.  I haven't tried that yet, because I would need more outlets.

When I thought it was my conditioner, I found it was another bit of gear doing the damage (causing the blinking) It can be anything! Finding which items was on great thing about using the Noise Harvesters! I was able to find each offending item. Like you, but at first, I thought it was the small Adcom conditioner causing a problem. NO! It was an item connected to it.
SO I would suggest the Furman is not the problem, but something plugged into it. The noise can travel a long way. Though I do find my Furman blocks from the small power to teh main power, but not between the individual small duplex. The Furman also block from outside, or from inside to outside it.PS: I made my own multiple outlets devices when I did not have enough outlets from the wall. From the wall is also from the wall to a pair of additional duplex!!
