This crt does not have deflection coils but internal plates which electrostatically atract electrons. And those are led's, they already had them in 1989.
Oscilloscopes use electrostatic bean deflection voltage potential on internal plates. TV CRT tubes use electromagnetic deflection with external winding (yoke).
Front to back switching was (is?) a common safe design practice. Basically, it keeps all the mains voltage in one place (e.g. on one pcb) and well away from the front panel controls.
I have a Hitachi VC-6023 Dual Beam scope of similar vintage to this. I have had it for over 20 years and it was quite old even then. However it still works and is the only scope I own. Back in the 1960's I built a Heathkit oscilloscope, about 3" tube and all valves. In the 1980's I worked with a 68xx development system with a separate twin 8" floppy disc system. When it was thrown out I could have had it but just couldn't lift it! Interesting to see the old stuff, brings back happy memories. Bob
Hey Electronoobs. Nice channel, great content. This vintage video is interesting. But maybe you could also point out which components may be worth salvaging for usage in further projects (e.g. old stepper motors, when you teardown old scanner or printer, and how can you run them, etc)?
wave soldered, this was before pick and place or surface mount also, LEDs from that era were mostly red, or dim green, no yellow or white so the backlight is not LEDs, just regular old filament bulbs
This was good, but I found it to be more of a showcase then a tear down. I was expecting to see some components flying, a little harvesting... that sort of thing.
I once fixed this old vintage oscilloscope. Took me about 2 days to figure out what was wrong with the scope and it turn out that the electron gun had some worn out components. Couldn't figure out what was wrong with it exactly. Luckily I had another electron gun from another vintage scope so swapped it out and now it's working just fine.
Getting to know an analog oscilloscope first has - in my opinion - many advantages. It has a true real-time display, no functions that are hidden 3 layers deep in some menu and immediate reaction to all knobs and switches. I would have expected something more of a "teardown" video, also the first 2 minutes out of a 10 minute video are dedicated to your sponsor, which was a bit long in this context.
Those ol Scopes opened many doors of knowledge. I would still welcome a Tektronix 435B I learned on. I would be right at home on that leader scope. I'm sitting here snickering. I would have gone to great lengths to own a scope like that back in the days. It never happened. Simply out of financial reach. I still don't own a decent o Scope.
Hey electronoobs I really love this channel.. and I've been following it for about a year now.. I was wondering... can you take the ideas/circuits posted on your website and try to create them? That would be a good content for UA-cam don't you agree?
Hi and thanks for the support. Are you reffering to the circuits other users are posting on electronoobs.io? Because the circuits from electronoobs.com are all already tested in my UA-cam videos! Keep up!
@@ELECTRONOOBS Well the Problem is that if i want for example place the ne555 I See that tere are no lcsc companents but if I search for it on lcsc there are more than two parts available!!
@@startobytes I have the same problem. I think is their server problem becasue now is holiday in China. I search for any compònent and they never appear in LCSC SMT category. I hope they will fix the problem soon. For now you have to search the component on LCSC manually each time...
Try to find Soviet oscilloscope from 60th-70th. You will find out how "true" devices that's gonna last for centuries look like. :) But go to gym first. ;)

Hey pls work on making your own 3d printer using arduino marlin framework. You are doing great 👍
Forgot to say..great idea, I love a look at what made it all possible !

Still we are use this stuff for measuring waves in our college😇😅😅
We use them too. From the University's perspective, they're affordable and get the job done.
In our college too 😂
Using old components are not bad at all, it makes you learn how it works
Good review
Hey Electronoobs. Nice channel, great content. This vintage video is interesting. But maybe you could also point out which components may be worth salvaging for usage in further projects (e.g. old stepper motors, when you teardown old scanner or printer, and how can you run them, etc)?
Yes, taht would be interesting, but for a different segment. Maybe "What to salvage" or so... Thanks!
Teardown videos are never bad.
wave soldered, this was before pick and place or surface mount
also, LEDs from that era were mostly red, or dim green, no yellow or white
so the backlight is not LEDs, just regular old filament bulbs
actually I believe the crt is electrostatic so no deflection coils
I'd like to see something with tubes, like an old military radio.

Pretty interesting electronics in there, dude! Really nice! 😃

Superb New Video Series!! Go ahead for the Teardown Show!! Waiting for TV Teardown!! Best Wishes...

thanks for this video, this brings back some old memories :)
I enjoyed it. Good job
I like this form of video , also repair videos could be great two , keep them coming !
Nice video...looks like it came out of the same factory as my TELISTRUMENTS scope..
Peace.
What is the Intro music
Great video sir, can you please make a video on bit manipulation, bit math and how to set the register and counter of atmega 328p
Yes, I put that on my video list!
Great!
I'm vintage and I'm awesome.
I need more of this.

Tear down a classic old record player or a DVR
Hmm, that's interesting!
FULL BRIDGE RECTI.....
Oh wrong channel
Nice tutorial
Can you make a pic ics programming tutorial please?
I'm working on that. Since I don't have enough experience with PICs, that's a bit difficult for me, but I'm collecting information...
@@ELECTRONOOBS thank you very much, I love your tutorials
What is the little digital scope called?
DSO-203
Ss we need a lot of tear downs 😁😁
interesting as always
Hi, I have a Problem using easyeda. I have no parts from easyeda!! Please help
What is the problem?

@@ELECTRONOOBS But I don't know how I should do that. Please Help me.
Hello, what is the update about ESC kickstarter project???
For now there won't be a kickstarter. Kickstarter is no success...
Moore Vintageeeeee! ;-)
Make detailed video on total working of dso vs cro
Great keep going
Why don't you start a repair series?
It's awesome
Super bro
Still my college uses this type of scopes
Do I get free coronavirus by ordering a pcb
Point to be noted
Cool, but i was hungry for more info 😋🤤
Plz extend time for the working of instrument.
Nice
Great.
TV ,radio,walkie taklie etc would intresting
Eu tenho um osciloscopio, Aiwa com trinta anos de idade e os cupins comeram o manual com os esquemas.Alguem tem esse manual?
First teardown
sir please one oscilloscope giveaway
Can u make a robotic hand
a little bit disappointed...
Could you please spend some time to talk about the circuit inside, not just the components?
I'll try to improve that
The banana sells it
Just one second diffrence between electronoobs and explainingcomputers upload time.
🤩👌👍
My Leader 1100 is vintage?! I guess that means I'm vintage too. Crap.
Try to find Soviet oscilloscope from 60th-70th. You will find out how "true" devices that's gonna last for centuries look like. :)
But go to gym first. ;)
Why every videos including a banana??
For scale
No bananas will be harmed because of its low conductivity :-P
Give give away s
