Audiophile Receptacle question

You can use 12/3 or 14/3 Romex. The braided 4-wire is for 220v ranges & dryers. It’s braided because if it were solid you couldn’t pull it through studs and joists. Canceling EMI wasn’t really a consideration although it may work.

It’s not braided.

Some 3 wire + ground has a spiral its entire length. I have seen some that is flat.If using NM-B (Romex is a Trade Name) for best practices use 2 wire with ground.


If shielding is desired use 2 wire with insulated ground MC aluminum armor cable.
3 wire with ground (4 conductors) is not recommended be it Romex or MC cable.

@jea48 and yes; Romex is a brand name. I was using it like I would say "I need a band-aid" instead of saying "I need a sterile adhesive strip" or kool-aid instead of powdered drink mix or Kleenex instead of boxed tissue.

@ zyphryx
I meant no disrespect. Read any of my posts, I always say Romex is Trade Name for NM sheathed cable. Even when it is me that mentions Romex in a post. Been doing it for years.

Best regards,
Jim

Wait a minute, if you are using a vintage amp, are you not supposed to use the vintage plug ( two pin...non grounded) that came with it! Plug that into any wall outlet and you risk....well you know.
Change the plug on the amp end to a decent three pin grounded...

Not so fast. It may not be a simple matter of just changing the 2 wire power cord and plug to a to a 3 wire cord and plug and ground the chassis of the amp. The OP needs to get a schematic wiring diagram for the guitar amp. Some AC line power wiring modifications will, may, be needed.

Hey guys...noob here. With one of these outlets you’re referring to, I still need to buy and use some sort of surge/power protection right? If so, is that going to screw with the clean power coming from the outlet?

First, the receptacle does not clean the power. If there is garbage on the AC mains the outlet will pass the garbage through its electrical contacts. Garbage in, garbage out.

As for the use of a surge protector at the equipment end.
It’s not the surge protection device in itself that may affect the sound of an audio system. It’s the chain of the addition of the device in the AC power delivery circuit. In other words the quality of the plug, power cord, and receptacle outlets used in the construction of the SPD (Surge Protection Device).

If you are wanting surge protection the first line of defense is to install a Whole House SPD at the main electrical service panel. If the audio equipment is fed from a sub panel then an SPD needs to be installed there as well. Last line of defense is at the wall outlet that feeds the audio equipment.
