Did you know there were wireless remote controls in 1940?
There were -- for your top-of-the-line Philco radio-phonographs.
Did you know there were phonographs that worked kind of like modern CD players?
IN 1940, there were -- on your deluxe Philco radio-phonographs. The electronics giant's Beam of Light record players were as easy on your 78s as they were hard on your bank account at the end of the Great Depression.
When you dialed up the phonograph on your radio-frequency remote, the tone arm would come down on the record, a lightweight sapphire stylus with an attached mirror would lower onto the record and reflect a light beam off of the moving mirror to a photovoltaic cell, which would modulate electric current into electrical impulses that would be amplified and . . . voila!
If you love old electronics like I love old electronics, it doesn't get much cooler than this. The miracle of modern technology -- 70-something years ago!
And the glowing tone-arm head just looks cooler than hell. The whole thing is just cooler than hell.
