Hello again! It’s time for a new and exciting episode of CP Electronic’s “Old Tech of the Week”! Today we’re looking at a beautiful piece of Canadian technology history, the Dominion Electrohome model 7B52M1!
Manufactured in Kitchener, Ontario around 1938-1939, this was a type of radio known as a “farm radio”. Running exclusively on battery power it was designed to run on heavy, multi voltage dry cell batteries in homes that had not yet been connected to the electrical grid. That’s right, before streaming, television, or even widespread electricity, these radios were the centrepiece of the rural Canadian home.
They use a 5 tube Steroheterodyne circuit, allowing it to pull in distant AM stations with surprising clarity. I can just imagine the family sitting around listening to this with the comforting warmth of a wood fire in the background.
It also features one of the most satisfyingly clicky power switches we’ve seen yet. They just don’t make things the way they used to!
We’ve also included an old CP Electronics receipt we found tucked inside of the radio. A little peice of our own history as well!
We hope you liked this one and hope to see you again next time!
