    Amazing. Very much looking forward to seeing the next bout.

    It is one of my 3 oscilloscopes, I bought it many years ago and inside and out, it looks like it just came out of the assembly line. I don't recall ever using it.
    Thanks and take care.

    I saved an EICO Mod. 460 O'scope from the trash pile at a repair facility I worked at in the '90s;
    I haven't looked at it, but a recent move uncovered it and I have it on my to-do list when my bench is set up at my new home...
    Thanks for posting this video; yours looked really clean!

      Yeah mine's in pretty good shape since it's been in storage so long and rarely used since I got it as a teenager.

    I just got the same model from a friend. His has been in his attic for maybe 50 years. I appreciate seeing exactly how to bring it up slowly, as so many recommend. I didn't see a followup video in your listing. Can you reply with a summary of further work you did on this scope? Thank you.

      Sure Duane, After making sure it would stay running for an hour or so, I went in and tested all the tubes. (They were all original and GOOD). Then I unplugged it, discharged all the electrolytic caps with a 100 ohm resistor. I went through and quickly checked the resistors in circuit (you can do that on vacuum tube devices without having to desolder one side. After replacing all the out of tolerance resistors I started replacing all the capacitors. I left the disk caps in there since they rarely go bad. I had most of the Electrolytic & paper capacitors in stock but not the high voltage (1500 Volt) ones. I was able to get those through Mouser. After replacing all those capacitors I just went through the alignment procedures according to the Heathkit manual. Very easy and enjoyable restore. If you have any more questions don't hesitate to ask. -- Good luck! ...Dean

    I have this same scope on my bench downstairs. It was my Fathers. I'd love to learn how to use it, but right now, its just a reminder of my youth.
    I also have the Eico 324 Signal generator, and Eico 249 Voltmeter/Ohmmeter.......Great video...

      They are easy to learn how to use and even more fun to play with, especially if you have a signal generator to input a signal. You can get an assembly and instruction manual here if you don't have one... pacifictv.ca/schematics/eico460manual.pdf

      @@DVRproductions52 Thanks for the reply!! I used to play with it when I was young, plugging in a microphone and watching the waves, but these days, other then that, I also tinker with all my vintage amps and would like to learn more about using it as a diagnosing tool. I do also have the Eico signal generator, but the lead is shot, a I would love to learn to use the generator as well...I downloaded the manual, thanks again!!

    Thanks Michael. I also own (3) scopes but I use my B&K the most. The EICO holds a special place for me since it was my 1st one of my younger days.

    had one of these, some caps were going bad and the transformer crapped out sadly, now it'll be a part donor for projects and such

    I'm picking up a Eico 460 tomorrow. How would I discharge the CRT? Is there a ground lug on the power cord, should one be installed?

    • @DVRproductions52
      @DVRproductions52  3 роки тому +2

      Ya know there really isn't an anode cap like on TV's & monitors. I'd just discharge each pin on the neck with a 100 ohm resistor. As for the the power cord, you can use a 3-wire ground but it really isn't necessary since the EICO has a transformer in it. Another reason to keep it 2-wire would be to keep the input jacks truly "floating". If you notice there is a removable ground strap on the input jack (ground to chassis). To keep the ground at the same potential as your unit under test. (Radio, amplifier etc.) -- In short, I don't think it matters much. For these older scopes, I prefer the 2-wire power cord myself.

      Hi Mason, the primary function of an oscilloscope is to display a graphical representation of electrical signals as waveforms. The horizontal axis (X-axis) typically represents time, while the vertical axis (Y-axis) represents voltage. Oscilloscopes are invaluable in troubleshooting faulty circuits. By observing the signal, you can identify issues such as signal noise, distortion, and unexpected signal behavior. Hope this helps you understand the value of an oscilloscope.

    My first scope. I wired it from a kit.when I git drafted into the army I sold it. I truly believed that I was not coming back from Nam. What I didnt sell I gave away. Low and behold the army sent me to Germany.

    • @DVRproductions52

      That's the way it goes in the service isn't it? I was supposed to go to 'Nam in '72 but a last minute reverse screw-up of the orders stuck me in Wyoming for 4 years instead. Not complaining though.

    If it were me, I would replace all the caps, if not physically leaking they are more than likely electrically leaking.

    Great video, but please get rid of this annoying background sound track. Incredibly annoying and distracting and your presentation stands great by itself without the need for some questionable audio "enhancement".
