Outlets with 2 prongs are very rare, usually only found in very old homes. If by some chance you need to plug a device with 3 prongs into an outlet with 2 prongs, you can buy something like this https://www.amazon.com/GE-Polarized-Grounding-Adapter-14404/dp/B00B7PK1TC
Get one of these for each power plug, it should fix it.

Source: had the same problem. These fixed it.
I recommend getting a three prong to two prong adapter for your scope so It isnt grounded on the power input/chassis.

One channel to each grid. Nothing in the input jacks of amp, volumes turned down. The only dc offset you should see is whatever the fixed bias is set to. You could pull the power tubes and disconnect the fixed bias to be sure.
It's a ground loop. I don't know if those have a ground lift switch. But you can get an adapter.

You mean one of These.

Yours didn't work because you used \ before the [].
Or ground lifts.
Maybe try a cheap cheater plug to see if it's ground noise?

Edit: Maybe try one on your turn table as well. If the noise is from the turntable then anything after that will likely pickup the same noise.
You could try that. Cheater plugs are cheaper https://www.amazon.com/gp/aw/d/B00B7PK1TC to test a theory.
I assume you're plugging the speakers into a 3 pronged outlet? There could be a ground loop between the speakers and some other device in your house- cable TV, telephone, etc. You could start troubleshooting by getting a 3 prong to 2 prong adapter like this and see if it removes the interference. (Note: this is just for troubleshooting and you should not permanently power your equipment without a ground, as it is unsafe)
There's also a possibility that the interference could be from radio frequencies, which is a completely different issue.
Probably the simplest, easiest fix would be getting a noise attenuating power supply like this or this. They are made to help isolate your audio equipment from both kinds of interference. This might fix your issue.
Hi OP. What country do you live in? Curious what your mains is and whether you have a building ground.
You likely have one of three issues here:
Or you can just buy one of these so you can still use the ground when you can.
I had this problem and I came up with a couple solutions, depending on your budget range. You could be like me and buy a power conditioner for the speakers to give them clean power, if you feel ok with spending like $100+. Keep in mind that this may not fix your issue, but it's always good to keep your studio equipment on clean power.
You could try isolating the power for the speakers. Grab an extension cord and see if plugging them in to an outlet in another room helps. Sometimes you'll run into issues there and that could be an easy fix.
Also, one thing I'd for sure recommend is lifting the ground of the speakers. This can be done with an adapter like this one, although I HIGHLY RECOMMEND not getting them on amazon and just going to Home Depot and getting them there, they're like $.70 a pop. The ground lift helps A TON with extraneous noise, you'll notice on many DI boxes, there is a ground lift switch that can help with stage noise, it's the same concept but just with your studio monitors.
Buy a 3 prong to 2 prong converter from a hardware store to push the plug up an inch so you have enough room to plug in something under it
One of these.
Get one of the cheater plugs (that doesn't have the ground plug) and try plugging the monitor speakers into that.

There's that too.
I have never used one of those. What i’m talking about is one of these:
https://www.amazon.com/gp/aw/d/B00B7PK1TC/ref=mp_s_a_1_1?ie=UTF8&qid=1518871306&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=ground+lift+plug&dpPl=1&dpID=41dPZcX6HSL&ref=plSrc
Both devices will likely get rid of your hum. Whether the $80 one is actually any safer is another question, and one that i’m unqualified to answer.

I know this isn’t what you asked about, but you can get adapters to make 2 prong outlets into 3 prong

It’s likely not a permanent solution but it’s a quick fix you can use to get your toaster working while you figure out the long term.
