I remember they got surplus stock of big old Burroughs Nixie tubes and circuit cards full of huge naked reed switches originally intended for telephone switching?
My Dad taught me how to do high quality soldering when I was 9 or so. I remember mounting an old tube TV power transformer in a box to power an elementary school science fair project where I recreated Edison's light bulb experiments by winding various types of iron wire around a large sewing needle to make tiny coils and knowing that vacuum and gas apparatus were out of reach for me at the time.
The large amperage 6. The higher voltage taps were stubbed and insulated for safety.

It was a nice sciencefair project actually, kids liked seeing the filaments glow briefly and then burn open. Good for elementary school.
At 12 I was building simple audio oscillators that used two multivibrator circuits so they warbled. My Dad wanted a loud noisemaker for the business garage so I hung a power transistor and a big scavanged speaker at the end and the warble would cut through a lot of engine noise.
I think I built that when I was like 13 and that loud thing kept running for a decade at least. After a few years it surprised somebody a bit too much so he put a pot or resistor in series with the speaker to drop the volume and it kept running for many years.
I could do a one off pretty fast. That's the progression.
In WWII, they worked on radar, improving it and finding that they needed to move up in frequency in order to get good enough definition. In doing so, they helped pave the way for more use of those higher frequencies after the war.
They were able to get tubes to transmit up there by making new types of tubes but had problems with tubes that operated up there. So they went to crystal diode mixers, and went back to the "cat's whisker" of the early days, except making it more stable, so you didn't have to fiddle to find where on the surface there was good operation.
And that caused the 1N34 to come along after the war, and it caused Bell to look at the transistor after the war.
I forget the title, but there is a book about this, something about the invention that changed the war, which is interesting in telling the story of Radar development during WWII, and its impact after the war. I noticed something interesting related to the 1N34 a few years ago.
I had downloaded a s copy of The Radio Handbook and one of the people thanked at the beginning was Rufus P. A name that was quite familiar in the hobby electronic and amateur radio magazines at one time.
SInce I remember his articles about solid state devices, I assumed he was a relative newcomer, but no, he'd been involved since the earlier days of radio. SOme of those writer's names were so constant, yet we knew so little about them other than what they published.
I got curious, and looked, and it turned out Rufus P. Turner was black.
He got a platform, at a time when he might not if people knew he was black. When I got interested in electronics the local library had one of his books from the fifties, interesting projects, that I took out endlessly since there wasn't much selection.Germanium Glass Diode.
The current flow through the circuit and voltage across the diode is measured and. Data sheet is similarly sparse.
So they went to crystal diode mixers, and went back to the "cat's whisker" of the early days, except making it more stable, so you didn't have to fiddle to find where on the surface there was good operation. Used in all type Second trial to improve calculated datasheet model compared with manufacturer model and default model.
Ratings and Characteristics of Sylvania Germanium Diodes Our model grossly over states current above 1 A. They hinted at robotics back then but if you look at the old Teddy Ruxpin ads on Youtube compare them with Furby of today, Teddy Ruxpin looks really sad with a cassette tape shoved in his backside.
