Hey Don
1954 on that ARRL manual .... not too many yrs before I was born ;)
Relative to me, that would make you a teenager. :D

Let's just say in 1954 i was in 3rd grade... President Eisenhower added "under God" to the pledge of allegiance.... Navy launched the "Nautilus"....

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.
Beauty is in the eye of the beholder. :oldwink:
I consider first hand information like this to be like peer review information. I'm going to change it to the 5U4. Thank you. :)
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 looked through my collection of vacuum tubes for a 5U4GB

5u4_std_1.jpg


and only found a 5U4G (which is more beautiful IMO)

5u4g_6.jpg


but the filament was open.

So now I have an order in for a used 5U4GB and a new-old 5U4G.
I'll post a pic of the power supply with the correct transformer 5U4GB vacuum tube when it arrives.

When I was very young, before starting school, my parents had a tube type radio that was outside of it's enclosure. They kept it on the top shelf of a cabinet where I could not reach it, for obvious reasons. 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.

I did a little collecting of old stuff myself a few decades ago. I still have some of it, but not at my current location. I may have some pictures on my hard drive. If I find them I'll post them here.

So I'm not alone in how these old things sparked my interest in wanting to know how they worked. :approve:

While I've been waiting for the 5U4 tube to arrive, I've had time to take some pictures that may be of interest to some of our biological science members.

This vintage light bulb has a thick spiral carbon filament and has these markings: North American, (NALCO), 4CP 110V
It was used as a therapeutic heat source heating, for what I think are, tools for delivering blood absorbers and blood coagulants to the nose; from what was left in the vials I had to clean. I removed it to be displayed in one of my old surface fixtures and put a similar size blue bulb in it's place, which makes a good "night light".

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.
Very cool, impressive and beautiful collection, dlgoff! :)
If you have any thing old and would like to share a photo, please do. It's all beautiful in my mind.
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:

Telefunken tubes:

Mullard tube, unknown tube, "opened" tube and a Luxor Radio tube case:

HP-22 and HP-27 calculators, and a HP case to them:

Very nice. I really love the tubes. Especially the DY 87. Thank you for sharing these.

They arrived today and I decided to us the G type since the voltage regulators are of that type.

I added a 30,000K color temperature fluorescent tube and some more chemicals (glitter) to the chemistry glassware shelf. This revision goes out to Borek, who has enriched my life over the years.

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.

So it wasn't a Beckman Instruments Helipot? Interesting.

Don,
Excellent video, and your probably correct that it had a Helipot buried in it, but assigned a product name to the whole thing, inclusive of the indicator rings.

I'm still moving on this Beauty project. I made some shelf room by putting the fluid gauges in a shadow box and did some restoration work on the old electrical meters which will go into their shadow box.

Stay tuned. Beauty via old Telephone Stuff coming soon.

I'm so happy I could kiss a duck on the beak after finally rediscovering this technology
That's the smallest "decade box" I've ever seen. Not like the ones I used in Physics II Lab. :oldeyes: Do you have one?

Speaking of small. This is the smallest "Variac" I've ever seen. It's used as a light intensity controller for a cystoscope diagnostic light. It's old and is stored in a cool wood, felt-lined box. The variable secondary scale has 14 divisions from DIM to BRIGHT. :oldtongue:

I'm getting close to getting the telephone stuff restored and displayed.

Here's how the fluid gauge and electrical meter shadow boxes turned out.

The telephone project has taken a tremendous amount of time. It's hooked to my home phone line and just made my first test. Good dial-tone. I'll do some more test later. I won't be cranking the generator though. Fairly sure I won't get an operator asking what number I want if I did crank it. I'll upload some before pics later.

Here are some before pics.

It had some previous work in the past. Note the uneven glue job.

ringerbox(unrestored).JPG


It was really dirty inside.

After it's been taken apart.

Here's the clean wood. The front (door) has been re-glued.

I had to make several tools to get the dents out of the candlestick (receiver/transmitter & stand)

Here's the door glue fixture.

Don,
thought of you when I saw this advert on facebook in Melbourne city far to my south ....
https://www.facebook.com/events/1436964459929586/

there's going to be so many items there you would love to get your hands on :)

If it had been in my city I would have gone and had a look for you and may got some gems for you

Everyone need a little beauty in their lives. One of those gems belongs in your home.

Your thought gives me more beauty Dave. Thank you.

Now this beauty is very useful. It's the Heath Kit V-6 VTVM. I repainted the box and couldn't duplicate the color exactly but it was close.
