Netgear Riding On Top Of AC Causing Havoc

I have been working on a new line of all valve analog high gain circuits.

However I continued to have what appeared to be a low frequency 120 cycle oscillation.

I interfaced preamps with power amps of many heads to deduce the culprit.

I finally thought well perhaps the grounding in that part of the home had
lost integrity. Nope, not it.

Scratched head. Then the lightbulb came on!

I live in a new 2.5 story 3,000sqft custom house. The WiFi is in my office upstairs. In order to get a signal out to our suit downstairs on the opposite end of the structure I needed a netgear WiFi transmitter that traveled on AC to a receiver plugged into the AC of our room for Netflix etc...


Eureka! That was it. But damn if I did not learn a lot about elevating heaters, isolating grounding schemes etc... in this short time. EVL is about ready lol.

Yeah, those ethernet over power device and tube amps are incompatible. Best to inest it something like a couple of google wifi points and make a mesh in your house

Right. I’m certain it is always there but not apparent except for one model of a modification which is really high gain.

However if it does become an issue that’s exactly what will happen.

Thanks for reading and posting.

What does this sound like? I randomly/occasionally get a wierd/objectionable high end hash in higher gain amps. Other times I don't hear it.

I have a Furman AR-1215 on the way which should resolve it but just curious.

Here it comes across as a 120 cycle "D♫".

I went through the same thing you did. It was very noticeable on a 100 watt metro build with stock filtering. My other amps with 180-220uf power filtering were good to go.
 
Just ran into this and really appreciate this post. I’ve got my practice amp in the tv room and have always fought with terrible buzz. Turned off & on the tv, cable box, every lamp, light, name it in the room - even went down a rabbit hole swapping volume pots / jacks in one of my guitars. Zero buzz / hum downstairs in my guitar room. Hmmm. Sure enough - wi-fi booster plugged in the wall of the tv room! Now I know 2 things: no, I’m not crazy or hearing things and 2) my guitar is wired just fine!

Great to hear. This is why I posted this. So glad you got it worked out.

Yeah, any high voltage will mess with WiFi.
Where I volunteer we had to ad a Cat 5
cable to get the WiFi in the next building.

Then added a WiFi repeater.
But, then again, any thing
pumping voltage out will mess
will a normal wireless WiFi.

Even having a cell phone next
to the WiFi transmitter can goof things up.

Now we have a WiFi repeater and a Cat5
cable in the room that we do Zoom on.
We can use ether or both.

I did networks in custom houses
for a few years and ran cables
every where, but this got messy
and just added a new modem
at the other end of the house.

And I just found out that
not all older pre Gen 5 netcards
will work 100% with the new Gen 5
wireless, I mean it works?
But is not running very fast.

Can't help but think of this interview
SRV did around the time In Step come out.

He cut holes everywhere in this house
and ran mike and guitar cables every
where and that is how he recorded.

I mean he hacked things up bad.
Pretty funny

Wow lol on the SRV. I never was aware of that.

Thanks for reading & posting.
