I liked the one showing the current limiting incandescent lamps on the vacuum tube aging device, but where is the rest of the magazine?
Made in USA electronics.
We did not even have real public TV at all in the 40s... But projection TV had been invented as early as 1939. In Switzerland.
Sadly they were all water damaged and moldy. I cut off the covers and scanned them. After scanning I washed off my scanner.
I have a few of the mags left and will hopefully go through them to scan anything of interest and dispose of. Black mold to an archive is bad business. Although my archive is not some pristine, mold free archive anyway. If I find the article on the aging device I will scan it for you before trashing the mag.
You scanned them! Good work. Seems like most of the links to interesting items I see on this forum are never created by the original poster.
The image typically was peojected onto a large reflective screen. Basically one could project onto a small groundglass as backprection with the whole setup resembling a large tv set, but this likely was too much technical effort for a then rather small image. The system was called Eidophor.I wonder what the picture looked like in the projection TV. I had never seen anything like that. All the old TV's I've seen are the round, small tube models.
That's a pretty stylish electronic parts store.
Part of me would get a kick out of buying brand-new Western Electric 300B vacuum tubes.
But in 1947, where would I have to go to find proper jazz records? Or something by Robert Johnson?
When I was a kid and we had TV trouble my mom would have me remove the tubes from the TV and she would drive me down to Thirfty's. They had a tube testing machine. You would stick the tube base into one of the dozens of sockets to test the tube. If you needed a tube you would pull one from the under the tester that had a door and storage for various tubes.
