Old Oscilloscope, The Steps Needed For Restoration

This is "part of" the preparation process in restoring a vintage Heathkit O-11 oscilloscope. We walk through the some of the more necessary steps in making this old scope dependable again. I also briefly talk about it's validity on the test bench today. If you are interested in seeing a complete vintage scope restoration, leave your answer in the comment section below.

I randomly bought a scope today because it looked so nice and 5 hours later I got your video recommend with the exact same scope that's what I call good timing.

Thanks for the Videos and sharing your wisdom.

1962 high school electronics class. I assembled one of 3 kits the instructor bought for the class. The first one assembled when the instructor turned it on a lot of smoke came out. The kid who assembled it shorted the filament ckt and burned a bunch of paths off the pc boards(took the instructor a lot of time to un do the total damage done, lots of mistakes). When he was ready to test mine. He was nervous and asked if it was going to work. I said:"Oh yee of little faith, of course this one will work perfectly". Turned it on and WooHoo!! it worked perfectly. Lesson was follow the instructions. I am a ham radio/electronics guy and have lots of heath kit stuff. Workmanship is ALWAYS suspect. Most of them had something done wrong(many times I suspect thats why I got the thing so cheap). Loved seeing you video and it brought back memories. Bravo!

Great trailer - I will wait along with the rest of the gang for the main show - please.

I'll join the crowd and vote to see the restoration as well!

A restoration video of the Heathkit would be a informative watch to anyone interested in restoring ANY valve based gear.
Look forward to it.
Big Thumbs Up.

I for one would enjoy seeing a rebuild.  My O-12 is due as well, it's going on 57 years old!

For me personally, it's not that I have interest in old oscilloscopes, it's that I enjoy the way you older vacuum tube devices of any type. I would enjoy seeing the restoration for those reasons. Thank you, Mr Carlson, for your high quality content.

I had a barely working Mil. one from a 1940's submarine that I fiddled with as a kid. You have reinspired my enthusiasm to get it working again. Thank you.

Paul. I always enjoy watching you at work. I have an old Philips scope so would like to watch along as you fix this one up. Keep em coming. Graham

I had one of these scopes years ago before I got my Tecktronics 535-s6, I had quite a few scops through out the years, all my stuff is gone now but I still have a NLS MS-215.
I had to replace the batteries with a gel-cell and it works great, I just pulled it out now and after sitting for a few months I need to charge the battery.
Thanks for another great video, good basic tips.

I enjoyed the video.  My former neighbor was a TV and radio repair person in the 1950s.  He gave me his old Oscilloscope many years ago and it has been sitting in my work area for years as a reminder of him and for its impressive looks.  I've never applied power to it.  After seeing your video I'm tempted to restore it.  I would be interested in seeing you do one.  Thanks so much for doing these videos.  You are the best video instructor on the internet.

My favorite part of this video is "The Magic Smoke". I've witnessed this phenomenon occur a few times! And yes, please make a restoration video.

[stanleychytla]

I always enjoy watching your restoration videos. I had one of these scopes but disposed of it about 15 years ago. Now I wish that I had kept it!

[claesjalmelid]

You are making such high quality videos, and i really enjoy watching them.
So, yes please, i would really like to see you doing a restoration video of a vintage scope!

[Andrewausfa]

l like watching any old test gear being restored so a big yes please from me. I've got quite a few bits of the UK versions of Heathkit gear which still get used in radio repair. Don't forget that wobbulator you had either! Love to see that one fixed up :) Thanks - Andrew

Hi! I personally enjoy a lot watching your old equipment videos, I think old stuff have a *magical* touch, a mix of nostalgia and the "good-old fashioned rugged stuff" feeling. Keep 'em coming!
