Double Radio Socket

Dale Little

Is that a special container for a HAM radio or something? It looks like it’s from the 40’s or 50’s.

Ramona Jimenez

Check out the North American section on ‘s Plug Socket Museum website!

Sarah Gill

Thanks for all your help. My house is a 1921 catalog house, so it has a variety of different electrical components.

Dale Little

N arrett, appreciate the link. I’ve encountered a few of these before but never a radio duplex. It’s older than I realized.

Ramona Jimenez

I come from a family of electricians and this kind of thing always captivates me. Weird stuff seems to be a common sight in the field.

Dale Little

N arrett, it’s fascinating. I once removed an asbestos-lined wooden panel with knife switches and wooden raceways in an old building. It was still active. Always interesting!

Clyde Davidson

N arrett, I thought it was Photoshop until I saw it 😂

Wow, I’ve never come across anything quite like this. Such an intriguing outlet.

Emily Tremblay

The upper outlet seems to be defective

Martín Monroy

Do you know where it was situated?

Carrie Gonzalez

That’s a fresh idea for me. Well done Sonny.

Raul Hudson

That’s a relic from the 1940s. The top half is meant for an AM radio antenna. The slot on the right is connected to a grounding rod outside. The one on the left is for a single wire that acts as an antenna throughout the attic, and the bottom half is the power supply for the radio.

Is that meant for a rotary antenna?

Sarah Butler

That was my initial reaction

Alexandre Patel

No, the antenna wire and ground need to be connected to the radio, as well as power. This outlet’s presence likely explains why mixing low and high voltages in the same box or raceway is no longer permitted.

Lisa Young

I’ve never witnessed anything like it before…

Leonel Toro

Radio ground duplex. Super old, from the 1930’s – 40’s. I’ve only seen it once before.

David Urías

Was this from Russia?

Victoria Miller

Pretty cool stuff

Clara Slawa

That for old radio so you can tune in to European radio stations

Yandel Riojas

I lucked out and came across a NOS with the plug and box.

Just slip the inspector $200 in cash and he will approve it!

Old-school radio ground outlet, gotta love it!

Arnaud Johnson

That’s a sideways glance

Barbara Fonseca

Jeanette Barrett

Seems to be a 17.5 amp outlet

Marvin Watson

That’s the one

Aiden Margaret

My mom is Chinese, and my dad is Japanese….

Elizabeth Taylor

That piece is in perfect condition. I have never seen a wiring device from that era in ivory before.

Martha Olvera

A 17½ Amp outlet…

Variable frequency? 😲 Definitely not a plug for anything else. Maybe DC?
