Hi, Mr. Carlson... I am writing to cast my vote for a detailed restoration of the O-Scope! Thanks, for the opportunity to be counted. I do not have an o-scope to refurb, but I DO have some very OLD tube radios. Your videos are TOP SHELF!!! Steve (from Kansas, USA)

I think Mr C mentioned that Vacuum tube devices have much lower tolerances than digital. So 10% or 5% doesn't matter. I think partly because these things have tuning adjustments, if I remember my 8th grade electronics course correctly. That teacher inspired me to pursue high education in my 20s, and his lab looked a lot like Mr C's, with many, many devices on the shelves.

"There are those who present (and the audience to whom you present is left to do with information what they will) and then there are those that teach (where the audience is left with a full understanding of the subject by full explanations and examples)" You fall into the LATER category of the above statement - GREAT WORK

Absolutely a restore! That old electronic smell is like the smell of ozone with my old trains. It always leads me to a complete thorough restore. I hope this too leads you to a full restore, breakdown, analysis, and some good tests! Love these old electronic restoration videos Paul. You’re a true master in your field of electronics.

You can imagine the amount of years this showed what was going on to its owner. So reliable and loyal. Now, many decades later here it is, waiting to do it again. They don't make 'em like they used to. Thank you for keeping them going. Please restore it, thank you.

There is something beautiful about old vacuum tube oscilloscopes. The warm glow always give the device a special "soul." I grew up messing around with an old Heathkit scope that my Dad had. Seems to me my fascination goes all the way back to old "Outer Limits" shows: "...WE control the horizontal. WE control the vertical..." I particularly love a fine Lissajous curve on the screen!

I wish I could just get my hands on some of these cheap from swap meets and restore them, but there is nothing like that here in Reunion Island 😔 I still have a bunch of old Tek stuff from eBay to go through and fully restore though!

Yes, please restore this old-school oscilloscope! This unit is a Sylvania Model 131, which was made between the 1930s and mid-1950s. There was a larger CRT model, the Model 132. The Model 131 used to have a different faceplate scheme for lower serial numbers, while serial numbers above 2000 were built from the late 1940s through the end of production for the model. Both the Models 131 and 132 were built with the "I-beam" construction technique that hung the tubes (usually octal and loctal) upside down like automotive radios of the era. There are Model 131 schematics available from the Oscilloscope Museum. I'd love to see how you would rehab such an "old timer" from the transition period for oscilloscopes around World War II.

This old piece of kit is definitely worth a restoration and I'm sure everyone will look forward to seeing that. The old sleeving on the interconnecting wiring appears in excellent condition so I would guess it's probably been kept in a stable environment over the years. I note it has a 3AP1 CRT tube which brought back a fond memory for me as I used one when building an "old-style" panadaptor a while back. I was very surprised by the bright trace it produces at very low EHT. Great video as always!

Hey Paul, Yes I would love too see this rebuild on your channel ! Thank you for all of your shows and sharing your knowledge with us !😊😊

By all means do a complete restoration on this one! It is well-deserving of that! While you are at it, please, Please, PLEASE give the metal chassis pieces a through cleaning as well. I believe that once you change all the capacitors and possibly some of the resistors, this unit will be like new in operation! Looking forward to the restoration!

Awesome videos, I always learn something, also I try to remember what gear my grandfather had when I watch, I was quite young so I didn't get to touch anything, when he died it all disappeared. By all means I would love to see this scope restored, it will help me learn more about restoring old gear and what it can be used for, so that one day I can restore my Radio Frequency Labs 829D calibrator that I picked up from my local electronics shop that looks like it hasn't changed much since it opened in 1952,

Yes please, love to see this working again

As the guru who finally demystified analog electronics for me, I'm happy for any knowledge you care to impart. If you'd care to restore this 'scope I'll certainly watch it. Having seen most of your videos, I know the process fairly well at this point, but they're still worth watching for the "gotchas" hiding in the different designs. Off to Patreon, as it seems I have some catching up to do. 👍️

Full restore! It would also be nice to see a bit of how this would fit into one of the labs - what pieces you have, what you have that needs to be restored, just overall how things are going.

full restore would be great. Learn so much from your videos.

Go ahead Mr. Carlson . I would like to see it completely restored.

Full restorations are what's keeping me alive

Hi Paul. I really enjoyed this episode, because I actually owned one of these ‘scopes. Although I did not use it much, it worked very well for me. I obtained this unit from a friend over 50 years ago. Thanks again for the memories.

I didn't know Stromberg-Carlson made these. I once accidentally smashed a 6E5 tube in my Jackson condenser tester which was held in a spring clamp. It's a good thing I was able to find a nice and strong one which didn't cost too much.

Yes please we are very interested on full restoration and calibration !

Definately want to see it restored.

Thank you Paul for all of those great videos you have given us throughout the years. I have learned so much thanks to your channel and the electronics course you present so well. The way you go about explaining the theory,practice, and procedure to troubleshoot and repair such items is a very rare gift. I only knew one other man that possessed this special talent, and he was my mentor for better than 30 years dealing in mostly Amateur Radio .. Like you, a real electronics genius who knew his stuff! Thanks to you, I am slowly building up my lab. Some old test gear.... Some new. And in watching your vids, I have a really good grip on what to purchase. You have built up my confidence to “ dive in” and repair that old Tube gear! Now knowing what to do (To a certain degree) I have restored several old tube revivers. The more modern electronics, still elude me for the most part. But at least now, I’m not afraid to try...... Thank you once again! And keep up the outstanding work!

So nice to see another video - I was really missing you! :) I love the way the dim bulbs look. Well, the look of the whole variac / bulb / isolation transformer reminds me of the 1920s electrical design style.

Looks like my old EICO 425 scope. Thanks for the trip back in time.

Being dyslexic electrical schematics and such is beyond me being able to comprehend them. But I do enjoy watching you work.

I've had several old oscilloscopes over the years. Fun to play with. I picked up a Heathkit Model 0-5 at a church thrift store for $10. You are lucky that your find was not modified. Mine is modified and a schematic isn't the easiest to find. Someone had one on EvilBay with manual but they wouldn't make a copy of the schematic--no reply to my request. It has the classic goofy raster like this one. I once had an old EICO model from late 40's. It worked fine. It also had evidence of modification with extra holes in the front.

Come on Paul, you made fixing a coffee machine fun and interesting, and I don't even drink coffee. Restoring this old jewel should be even more enjoyable to watch as are all of your videos. Let's "git 'er done"

I like your videos. Two comments: 1) The L in Solder is silent; 2) Since there is oil on our fingers, it is critical to NEVER touch any conductor - such as pins or terminals. If that happens, the terminal should immediately be cleaned with 90% isopropyl alcohol. Steve S, Radar Scientist/Engineer, Raytheon SAS.

#1: I'm not in the US. I speak the "English" language, not the American version of it. Click "UK" dictionary.cambridge.org/pronunciation/english/solder #2: Seems like there is no corrosion anywhere on any of the contacts in this scope, do you think everyone that has been in this (since the 40's) has washed the contacts with alcohol? This isn't going into space in a sealed enclosure, and the voltages are not logic level or below. We are also not dealing with GHz frequencies, were dealing with kHz frequencies at best. There is a procedure for everything, but everything doesn't have the same procedure. Thanks for your comment Steve.

Loved your video of this old valve based scope, i'm an old engineer thats worked with B+W and Colour TV sets from the late 60's that were hybrid designs made for the uk market so have some knowlege of valve based equipment but i learnt my trade from 1970 by then most TV's were solid state, with a few valves. While fault finding i had acsess to Valve and Solid state scopes so i find your restorations of these early scopes very interesting, i never came across the wax caps or early electrolytics during my servicing years but do know these caps can go leaky or low in value hence the hum youve mentioned in your radio restorations. I would like to see the Silvania Scope fully restored, it would be a challenge to repair equipment like this as ive not come across any valve based equipment for years in the UK. Hope to see your resoration video on here soon and hope you have the time to get this scope working soon.

Great looking scope! Definitely show us the restoration. As one of your long time Patreon members, I’ve probably watched every scope and radio restoration you’ve done, but you inevitably include tips or insights that you have not mentioned before. It would also be interesting to see more of your behind-the-scenes processes: searching your bins for parts, showing actual repairs, etc. I know that such a recording would probably be split into at least two videos, but that would be fine with me and many others I suspect.

Dang so when i "invested" in a carton of fifty 5B/254M loctal tubes for experiments, 1st time i put one on my tester, i so got it so wrong! I had to unplug the NOS tube & reset things. It was so hard to remove & rocked it like crazy in the socket & then pulled it & reset things on the tester, plugged it back in. For a couple of minutes the filament glowed and i got some readings but then nothing! It was hot to the touch & the filaments were drawing current but were not glowing red at all! Later (1/2hr) i noticed the edges of the getter going white! ... It took over a day for the getter to totally go away, completely white. No cracks to the envelope so i guess i wrecked the pin seal unplugging the tube so rough. Then i found the socket, on the tester was a new modern one. It was just so strong on its locking compared to a quality original version! (Just neat to learn how i was supposed to unplug a Loctal, so thanks Paul)...
