Of course I'd like to see this restored. Like a lot of other things we took a first look at lately. Still can't wait until those restoration videos come up!
You do great work. I've never seen anybody better, who also has a deep understanding of electronics n all the components. I wished I did.( I was ee major but switched to comp.sci. I did finish 2 yrs elec. Cert. tho) but never saw anyone this good. Great Job. 👍
Paul, I watched your video on Noise this evening, I was amazed. I am looking forward to viewing your content to expand my knowledge, thanks for all you do and you can count on me for a patreon subscription. All my best, Stan N3PRK
Sure. Full Restore. Love to watch them. Trying to shift to doing instead of just watching. I know it takes quite a bit of lifespan to put these together. Thanks for choosing to do so. They are calming with all the junk going on today.
I'd love to see a full restoration and a short how-to guide on the usage of this scope. Love your videos, please keep them coming and a big thank you for everything.
I'd like to see a signal connected to the input, maybe just a sine-wave or audio output signal. Thanks for these restoration and repair series videos. It's great to see someone take on the older tube-type equipment and show how cool the older stuff can be. Kudos to you.
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)
@@MrCarlsonsLab Good day Mr. Carlson. Do you repair for the public? I have an excellent pair of Heathkit AA81 amps that have original ripple filter cans. Im afraid to use them, but have run them on 90v using a variac. Id prefer to have the cans repacked than altered otherwise.
I was surprised to see most of those resistors 10% , so I would be tempted to replace them with 5% or better tolerant . All these vacuum tube gear is worth a restoration. Good video as always
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.
@@toomanyhobbies2011 Depends on the instrument. If it's a condenser tester the film capacitors need to be tightly toleranced so the bridge will work in an accurate and repeatable manner.
@@douro20 they usually use mica caps... or on european stuff ,polystyrene... so when we see those ,we automatically know its a critical part in terms of value and stability....when they'd use paper caps or carbon resistors they can be off by 20% sometimes even much higher and it will work just the same if you adjust and calibrate the thing wether its a scope or a tv....
Yes please, a full restoration is definitely warranted! Your clips are both informative and thorough. "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
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.
Yes, Please if you would restore this together, I really look forward to your next project. I patiently wait for each video. You are one of the best of the best.
one vote here to restore please. great looking scope save it from the landfill. I love your electronics museum and the fact that all of your museum pieces are part of your test bench. Love your videos Mr. Carlson keep them coming!
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.
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.
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!
Paul ---- I vote yes on a restore video. I have an old Eico 460 scope to I'd like to rebuild/get working. I started in hobby electronics back in the 70's with 7400s and then 555s. I skipped high voltage stuff, now I find myself being drawn to it. In large part, your fantastic videos are corrupting me. You have skills I can only dream of approaching in time. You and your channel are a magnificent resource, plain and simple. Thank you for all you do.
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. 👍️
I have an old scope similar (I think it is a Devry? It seems to look like the same style this one is so YES PLEASE a full restoration would be great. Unfortunately the front sear on mine is not good. thank you
Harbor Freight sells and sometimes gives away a magnetic bowl that's excellent at keeping small screws together. And to all: if you sell OLD equipment but don't know if it is good then please cut off the power cord!! And if you aren't technical don't blindly plug it in to test!
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!
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,
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. Thank you, Paul, for what you do for this community.
I always look forward to and learn a lot from your restoration videos. I vote yes! Thanks for all your work on these and for sharing all your knowledge and experience.
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.
Thank God....I was going through withdrawal! :-) Should be out gardening but no way until I watch this. Thanks, Paul. Yes please....rebuild would be interesting.
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!
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.
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.
Always enjoy watching the old equipments tests and detailled repairs! 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!
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.
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!
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.
Absolutely, I'd love to follow you along while you do a full restore; how & where you find documentation ... to checking stuff, cleaning to where to obtain parts from, etc. The whole 'ball of wax' ... so to speak. 😉 Thanks much, Paul!!!
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.
Hi Paul... yes please... also interested in then seeing how you use an old scope like this... thanks again for another of your great vids... keep up the good work...it's much appreciated...
Hi Paul. Your videos are always packed with wonderful things to learn. Your commentary on different things along the way is also very valuable. One quick question though: Is there any good place one could get the kind of equipment you work on, on this channel? Thank you!
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"
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)...

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.
Hi Paul... yes please... also interested in then seeing how you use an old scope like this... thanks again for another of your great vids... keep up the good work...it's much appreciated...
Hi Paul. Your videos are always packed with wonderful things to learn. Your commentary on different things along the way is also very valuable. One quick question though: Is there any good place one could get the kind of equipment you work on, on this channel? Thank you!
Very easy access to the caps & resistors. Should be a fun resto job.
Yes rebuild it. Fun to watch you work.
Yes please to a video restore series. Thank you.
My first job out of college was for Sylvania Electric 👍
Definitely a restoration candidate
Full restore please Paul, you know we want it😀 TFS, GB :)
Yes, please restore. I love the look of that big old tube in the middle, looks like a double triode of some sort, not seen one like it before.
Rebuild it, your rebuild project are always very interesting and appreciated!
Such a neat layout there, looks like a joy to work on!
Another absolute banger of diagnostic & testing videos! Keep up the most excellent work!
LOVE these kinds of restorations! Thank you ! I have a Tek 545 that I need to restore - project for 2022.
I’m looking forward to this restoration And seeing it work perfectly again! It definitely deserves it😁
Yes, it would be great to see a full restoration.
I vote for restoration. Always love to see old stuff like this brought back to life!
Thank you for sharing. Excellent video, as usual. I would enjoy seeing that scope restored, and I look forward to the next video.
Obviously wanna see it come back to life super cool
Hello Mr Carlson, it will be great to restore this electronics time piece.
It is a great device and you do very careful work.
Always interested in seeing full restores. I have seen a few teasers from you recently. Kind of miss the 2 hour long restore videos :)
Absolutely YES! These things are great to see.
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"
Good show! That’s a really nice piece
Definitely do a rebuild video
I want to see you use it to repair/adjust something.

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)...
Glad to help Pete!
