Beauty is in the eye of the beholder.Indeed it came from a television; that's where we got parts in early sixties... a local dump sold scrap TV chassis for 50 cents.
Even though it was just the right voltage I used a different transformer solely because that one was so ugly.
You have a great memory Jim. I found a pic of the transformer I have used in the http://evilfurnaceman.tripod.com/id28.html [Broken].I consider first hand information like this to be like peer review information. I'm going to change it to the 5U4. Thank you. :)
So I'm not alone in how these old things sparked my interest in wanting to know how they worked.I think that was what first sparked my interest in electronics. The glow of the tubes, the seemingly magical way it could bring in sound from afar, and of course the fact that it could also be dangerous, made it very interesting to me. I wanted to know how it worked.
Very cool, impressive and beautiful collection, dlgoff! :)Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far.
The only electrical/electronic things I could think of were some vacuum tubes I've got (I don't know how old they are) and two Hewlett-Packard calculators, HP-22 and HP-27 from ca 1975-1978, here are some photos:If you have any thing old and would like to share a photo, please do. It's all beautiful in my mind.
Very nice. I really love the tubes. Especially the DY 87. Thank you for sharing these.The only electrical/electronic things I could think of were some vacuum tubes I've got (I don't know how old they are) and two Hewlett-Packard calculators, HP-22 and HP-27 from ca 1975-1978, here are some photos:
Mullard tube, unknown tube, "opened" tube and a Luxor Radio tube case:
HP-22 and HP-27 calculators, and a HP case to them:
So it wasn't a Beckman Instruments Helipot? Interesting.On the topic of ancient things, there used to be an ultra-precise multi-turn potentiometer that was great for building references. All I recall now are the Helipots, but this thing had rings within rings on the face. I cannot remember their name, but they were wonderful instruments.
That's the smallest "decade box" I've ever seen. Not like the ones I used in Physics II Lab. Do you have one?I'm so happy I could kiss a duck on the beak after finally rediscovering this technology
