I recently found a Tektronix 475A with the DM44, manuals, two P6063 probes in nice condition for $25 at a hamfest. Bought it, gave the switches a good cleaning and replaced the rear feet. It appears that it had been serviced a few years back because it was not suffering from any of the common issues these units have. Went through the routine in the service manual and could not find anything really wrong with it except the calibrator is about 200mV over spec.
Every time you do a $50 eBay oscilloscope or cheap online the eBay an online guys all raise their price the same day when everybody goes clicking and looking for cheap scopes, the price skyrockets
@@hxhdfjifzirstc894 you think the Australian guy is the person selling used analog scopes on US eBay specifically offering things like free local pickup in Florida and Seattle or wherever? How's that conspiracy work exactly?
I mean, I find this helpful. I'm looking for my first used scope, so it's good to see what excites him as good options. I'll just wait a couple weeks for prices to normalize, which I'd probably do anyway, since I want a good find.
Bought mine from the lessons from your last video. Went for 100 bucks but the seller provided a warranty, the scope had 60MHz and 1 Probe was included. And for the low end digital scope, I made one from a Raspberry Pi Pico overclocked to 2MSa/s
When I started my bench scopes were expensive and hard to find. Craigslist is full, I've been buying them and giving them away to students. By the way, I picked up 4 working Teknetics 2 channel scopes for well under $100 USD each. They work great!
I scored almost exactly that HP 54645 at a college selling old equipment. I paid $80. Universities are sometimes good sources of test gear, computer equipment, or even some office equipment. If they have a property disposition center anyway....
I bought 8 scopes in an auction back in 2019, Mostly LG Goldstar OS-9020g, but there were a few others in there as well. Tried to sell them for $50-60 a piece on marketplace and got my A$$ chewed out, finally took them down and just gave them away to folks who wanted them. But i got message after message from hateful people on marketplace saying old scopes aren't even worth giving away. I was horrified! Never listed anything for sale on that despicable place ever again!
I bet they also wanted your address so they could pull it out of your garbage can after they tried to price shame you, lol. I've done OK picking up "vintage" audio gear and test equipment on MP, only had one 2 person "Bait and switch" where the "seller" had someone else actually selling the item, that didn't speak English, and a Nakamichi receiver turned into my choice of 3 low budget models. Patience and persistence is key no matter where you look.
For $50 I got a beautiful analog scope with the digital multimeter. Iwatsu 100MHz scope in new condition. Just keep eyes open for local listings. Scope is in nearly new condition and screen is perfect.

My first brand new Oscope was a Hitachi V355 dual channel 35 mhz unit in the Reagan era. I needed a usable scope for business rather than wasting time with flakey used ones. It still works well today. In production we used new tek 2210 and we wore out the time base switches and vertical gain switches. Every unit made had tests where the production line used several different settings. Tektronix actually flew to SoCal and video taped time lapse to help believe that we wore them out slow quickly. Tektronix use to or still? Had this free gizmo at Comdex that had a waveform from hell that only a better scope would trigger on. My V355 would only trigger at one spot while the Teks could trigger all over the waveform. At one firm we had this Hitachi storage scope that had nice visuals but the trigger circuit was fair. So we used a tek scope to trigger and fed the output to trigger the Hitachi storage scopes. For someone new to Oscopes a better ebay seller can help weed out the junk and scam units.
Ah, Israel! I was looking for an HP 410B VTVM. They aren't cheap. But I found ONE, from Israel, that was reasonably priced. BUT....The bloody bastards had CUT off the cables. including the one with the RF probe! A 410B without its super-duper probe is like a vintage Ferrari with its V12 engine removed.
I picked up 2 broken Tek 465's for $30. This was just for parts for my working one. Got a front cover and full service manual in pouch (just those I think was worth the money). Narrator: He never got around to try fix the broken scopes.
most of the scopes I've gotten have been free from schools or oldie engineers who have a broken unit in their garage. the rest of them were broken cheap and local (but also ancient).
Don't overlook hamfests. Two week ago, I picked up a Tektonix TDs2014 - 4 channel, 100Mhz, 1GS/s digital storage scope with probes for $40. On the downside, while the screen is readable, it could use repair/replacement as the polarizer in the LCD screen appears to be failing with "vinegar syndrome".
I own three analog scope and all of them are up to date on components and fully functional one is 1 channel tenma for backup and audio work, another is 2236 100mhz and the other is 2465 300mhz. I got 2465 for free though i maintained it but i am scared of this scope because if it will ever fail, that will become a trash if hybrid is gone. The one i like most is 2236. My recommendation tough they are reliable is to own a digital oscilloscope from latest generation, if if you can find a used one, i would pick it and install heatsinks where ever i can to give it long life.
As someone based in New Zealand, the cost of shipping is a deal killer. Shipping is dead money. I use a freight consolidator/forwarder to provide a US address for shipping. I have purchased a HP multi-meter from e-bay USA, but the shipping cost matched the bid price. Buying gear on USA e-bay makes sense for really expensive test equipment where shipping cost is an insignificant part of the total cost.
I managed to score a Philips PM3055 and Kikusui COS5041 for free from the TAFE I study at. The Philips' glass relays have this beautiful sound to them every time you change the timebase.
I got an HP1740A at a hamfest, and later saw your three-parter on fixing one. Mine works perfectly, but now I know what to look for if it fails (rectifier). What would you have charged for 3 hours of Engineering diagnostic time? And thanks to those videos, I just bought ANOTHER DMM!
Outside of the "Voltage multiplier" failures on the HV CRT section, it seems to be a really well built scope. That issue makes it hard to get working again if you cant rig a modern suitable substitute for the old - failed part, don't bother buying a "Used - tested good" original one, as it is sure to fail soon after arriving just due to age, it's potted/sealed and you cannot access the HV caps to make it work again.
Picked mine up over 30 years ago at a parking lot sale. Surplused from a university test lab; was avoided because it was mounted in a 4U rack panel. Current calibration certs. Drilled out the welds and bob's your uncle. About a year later, a friend gifted me a Tek scope cart for it. Still going strong--it's what I turn to when I need an analog scope. Problem is that the case isn't painted, so it's not Tek blue.
I'm with you. I have a 465 on my bench next to a new Hantek and I use it all the time. It weighs as much as a small car but it works like new and I only paid $85USD. Not bad..

last summer I got my hands on a tek 453 and a BK precision 2120 from two different sellers for $120 for both shipped! the bK needed a fix and the tek was shipped horribly (some of the knobs were obliterated!) but both channels worked. found some dry solder joints on a transistor on the BK and now it sits on my bench and is working fine. the tek i'm still looking for knobs :(
I used to take pride in my antique test equipment, but it hasn't aged well, and repairing them isn't cost efficient for me. But being able to get modern equipment at such low cost is shocking to say the lest! Stuff that was a dream a decade ago is now a possibility!
I have picked up a 2ch picoscope locally recently for around 50 bucks. You are trading bandwidth for a modern interface and nice functions and you do need to connect it to a pc, but it certainly is an option for someone on a budget. :)
It's amazing how much of DIY electronics is searching for tools and components. And having to learn the hard way that what you ordered, isn't always as good as what you expected.
I just received a somewhat unique 'scope, that I bought from Ebay, for $100 (US), with free shipping. It's an HP 1200A. This is a 500KHz scope! WHY would I want such a narrow-band beast? I have several faster 'scopes, including a Tek 2002B. I'm really into audio, and that doesn't require a wide-band 'scope. What makes the 1200A appealing is 1), it has balanced inputs, and 2), its sensitivity: 100 uV/cm! It's perfectly suited for testing and aligning phono cartridges (THEY have balanced outputs), and can be used for moving-coil types, which have very low outputs. It has some minor problems, most of which seem to be due to dirty pots/switches, though it's usable as is.
I worked for an MOD contractor for a time as a trainee test engineer (late 80's), all state of the art gear there, and they had Iwatsu scopes. Not used an Iwatsu since then but always remember them.
My current scope is a Hameg HM204 I bought at an electronics fleamarket in early 2010s for something like 250PLN. A good dual-channel 20MHz analog scope perfectly usable for all kinds of audio work, with a built-in component signature tracer, but since I'm getting into protocol debugging and that kind of stuff, it's sometimes hampering me. Got a Leader LBO-5880, programmable jobbie. It keeps pulling control shenanigans and the guts are virtually unserviceable, a dense mess of PCBs with absolutely no schematics on the web. All the front panel controls are done with rubber membrane keys, failing a lot. Meeeeeeeeh. This thing didn't age well. Also got the Soviet S1-64 scope, analog with nuvistors. Got it for free together with a few power supplies from a tech university robotics association. Might be working - I haven't even fired it up; I'd rather start with an internals checkup, still gotta do that. It goes up to 60MHz which means it'd be the fastest one in my lab, but the size is so OMG it'll stay underneath my bench and work with dummy loads for amplifier testing, and as a fallback device. Plus it has a teeny tiny screen, 6 by 8 cm, not really useful. Used to have a ZRK OS102, a true beast, clearly inspired by Tektronix. Thing of beauty, joy for ever! All vacuum tube and none of that semiconductor rubbish apart from some diodes and FULL BRIDGE RECTIFIERs. Got it for free from an audio electronics repair shop when they were moving... It served a few years in my lab, but was too bulky for the space I had there, so I sold it. Now I wish to have one again as Tek is out of my reach financially, haha! Also used to have a Philips 2-channel 20MHz scope but it was pretty flimsy, it broke down at some point and since I still had the Hameg, I didn't even bother repairing it.
I picked up a Tektronix 2446 about 15 years ago from eBay, and I think i remember talking to the seller and the seller threw in a Tek T932A for free... so, 2 for the price of 1! Unfortunately, they both need servicing.
Meanwhile, here in Oz, I just got an email notification about a Tek "Tedious" 220, I briefly looked at, which is now going for $A570.48! I wouldn't pay even that many cents! Another delight is a company in Melbourne who have a Tek 7613 like my dead one, that they are asking $A549.99 for. I'm sure I saw a dead TDS series Tek last time for a low price, but it doesn't seem to be there, now.
The problem is, someone as ignorant as I am, needs someone more knowledgeable looking over my shoulder. With new ones there’s great reviews online, not least of all from yourself. Then we can compare specs within a price range and new ones from an authorised dealer come with guarantees.
I‘d take that 54645D any time. Used one at work for a long time and I think a colleague still uses it. Really well thought out interface, a y knob for each channel, what more do you need?
Rather than scanning ebay for old scopes one could look for dave's dumpster for scopes :P With dave getting so many new scopes for teardown review I am sure some of them would be going to the out as well........I am buying tickets to camp out side Daves office....:)
I had an Agilent 54622D which I sold because of not having space for it. I sold it with 4 analog probes plus digital probes pretty cheap (£150) and regret it until today.😢
Unless you really look for a scope in the pocket change region I wouldn't go for such old scopes anymore. Getting a 50 year old scope is probably more hassle than it's worth to a beginner, even if it was just for 50 bucks. If you hit the 200$ mark with your shopping you seriously ask yourself if you shouldn't just spend that little bit extra and get a new one instead that probably gives you alot less headache and is a fully features DSO. You can get the entry models of rigol and siglent for around 300 bucks already and you are kind of guaranteed that they work out of the box including probes that haven't been repaired 3 times beause the insulation started disolving 20 years ago..
I bought a £150 Tektronix 2440 so I know they can be bought out there. Sadly this one had a problem with one of the supply lines folding back when the timebase was dropped below a certain range. I've been trying to repair it but could really do with a pointer to an online repair group if there are any out there?
i have modern, but find myself more comfortable using old scopes i run a 2430a which i wouldnt recommend! but also several 2245a and love em ,24 series are far too overpriced and not really available in uk. the key is having one for spares or compare, if you cant locate a fault =swap boards and locate the fault by comparing voltages in the working one , "need a scope to fix a scope"
@@darrenmurphy6251 I have a spare 2440 that I bought as spare/repair. Sadly it's a different Rev and so the main boards are different in layout and so not much good for swapping out. I'll keep persevering with the fault finding, but I may just change the PSU current monitor resistor to overdrive the PSU a bit which hopefully will stop the foldback.
@Ja Ro They're OK for casual use, and are good enough for relatively simple tasks such as checking clock signals and data lines on old 8-bit computers. Adrian's Digital Basement has reviewed a few of these. Even a "100MHz" (which is really only a 20MHz) pocket scope is better than no scope at all.
I think the crazy over priced items on ebay is not so much somebody dreaming, but it part of a money laundering ring where the buyer and seller know each other and need to get clean money.
Oh mate, that is one thing in life that grids my gears, it's so annoying when they just change the format of a well established site🤬 dont fix what isn't broken....

Hello EEV blog rookie question are LCD screen scopes safer than tube style CROW’s? I want 20mhz bandwidth but don’t want too much x rays for the bargain.
Most CRT scopes operate on voltages well below the ~16 kV required to emit X-rays. X-ray emission was really only an issue with very early color TV sets, and most of the emission came from the HV regulator and rectifier tubes, NOT the CRT.
The sellers on eBay. Listing items with stupid, no hope prices are the equivalent of scammers in my opinion. I hope they "Only Receive Negative Feedback"
I assume your viewing base is Australia so it would be more appropriate to refer the Ebay Australia. The US market is large but the cost of freight to Australia from the US is off the planet and swamps the cost of any item bought. So maybe focusing on EBay US and excusing yourself saying it is not possible to cover all Ebay counties give more verbal dribble possibility but does not serve your audience needs.
About a year ago, I picked up a new Owon HDS2102S scope-meter for a little over $200 US. You get a 2 ch 100 MHz scope / 4.5 digit cat III TRMS meter / 25 MHz function generator. The batteries are two 18650 cells. This gadget has been an excellent addition to my tool bag and it would make a great first all-purpose instrument for a hobbyist. If one can swing $200, the pay-off is getting a set of instruments which all function to spec rather than putting up with dodgy stuff from eBay.
eBay lists price in big type and shipping in small type. If you want $90 you can list the item for $40 plus $50 shipping and some people fall for it. I find this a reliable way to filter out disreputable sellers.
HI DAVE. NO REALLY. THANKS ON THIS VIDEO. IVE BEEN TRYING TO GET MOTIVATED TO GET A $150 SCOPE AND I REALLY THANK YOU FOR YOUR LITTKE PEP TALK. YOU HAVE BEEN ONE OF THE MOST SINGLE INFLUENCES ON ME OUT OF EVERYONE. YOU ARE REAL DOWN TO EARTH AND NORMAL AS A THEN COME. A TON MORE THAN WHAT I CAN SAY FOR THE PEOPLE IN CDA IDAHO. ANY HOW. I THINK THAT SPOKANE GUYS TRYING TO GIVE ME THAT SCOPE. AS SPOKANES 17 MILES FROM ME. ANY HOW THANK YOU SO MUCH FOR THE PEP TALK. LIKE I SAID YOU ARE DEFINITELY ME BESTIE
Look at the shipping cost of some of thses so called "bargain" scopes you show. the shipping cost as much or more than the scope. so actually still no $50 scope as it would actually cost $100 or even more. so don't see your point as the shipping is crazy so again, no such thing as a $50 scope anymore. thanks for the video anyways.
If you are incapable of fixing whatever can happen to a scope then don’t buy it. Ive got 50 years in the E business and I bought a “ working “ scope by a bullshit seller. It took me many hours to find parts and fix it. Calibration was another story. Parts ate not readily available , information is sketchy and everyone who can fleece you is just waining fir you to enter their lair. Tektronix scopes are highly complicated using over engineering practices. They are not built for expedient servicing . Thats the analogue scopes too. Forget the digital repairs . A &50 scope is junkyard trash. You are better off looking fir a good TDS 200 digital scope. A working one can be had for $100
AGES ago I got a ISO-Tech ISR622 20MHz for about £20. Still in use, still works for me. Old school, low res, simple CRT...brilliant!

I used to take pride in my antique test equipment, but it hasn't aged well, and repairing them isn't cost efficient for me. But being able to get modern equipment at such low cost is shocking to say the lest! Stuff that was a dream a decade ago is now a possibility!
I have picked up a 2ch picoscope locally recently for around 50 bucks. You are trading bandwidth for a modern interface and nice functions and you do need to connect it to a pc, but it certainly is an option for someone on a budget. :)
Those HP scopes like the 54645D, have awesome UI and responsiveness. They are just so fun to use.
Thanks, you just made the price of all these scopes go way up.
It's amazing how much of DIY electronics is searching for tools and components. And having to learn the hard way that what you ordered, isn't always as good as what you expected.
I never could find a deal around $50 on ebay but did get a decent one for a 2215 on goodwill right around $60 luckily worked fine
I just received a somewhat unique 'scope, that I bought from Ebay, for $100 (US), with free shipping. It's an HP 1200A. This is a 500KHz scope! WHY would I want such a narrow-band beast? I have several faster 'scopes, including a Tek 2002B. I'm really into audio, and that doesn't require a wide-band 'scope. What makes the 1200A appealing is 1), it has balanced inputs, and 2), its sensitivity: 100 uV/cm! It's perfectly suited for testing and aligning phono cartridges (THEY have balanced outputs), and can be used for moving-coil types, which have very low outputs. It has some minor problems, most of which seem to be due to dirty pots/switches, though it's usable as is.
I got my Tek 2245A, from an honest seller in California, who included the original users manual!
How would some of the cheap scopes shown on this channel(at least I think) from AliExpress compare?
Ahhh.... As an Aussie, you clickbaited me in right there. Oh well, it worked lol.
My advice here would be pay a little extra and buy something with on screen cursors/measurements
Nice extra if you can get it.
@@EEVblog Count squares, then apply calculator + brain--not really difficult!
Is it really worth it to get those sub $100 old analog scopes when you can get a new portable digital one for $70?
A lot of the cheap new stuff is rubbish, until you get amongst things like Rigol & Siglent, & they are quite a lot more than $70.
Another smaller brand to consider is Iwatsu.
I worked for an MOD contractor for a time as a trainee test engineer (late 80's), all state of the art gear there, and they had Iwatsu scopes. Not used an Iwatsu since then but always remember them.
I got a real beauty for $120 shipped. Very happy 😀.
My current scope is a Hameg HM204 I bought at an electronics fleamarket in early 2010s for something like 250PLN. A good dual-channel 20MHz analog scope perfectly usable for all kinds of audio work, with a built-in component signature tracer, but since I'm getting into protocol debugging and that kind of stuff, it's sometimes hampering me.
Got a Leader LBO-5880, programmable jobbie. It keeps pulling control shenanigans and the guts are virtually unserviceable, a dense mess of PCBs with absolutely no schematics on the web. All the front panel controls are done with rubber membrane keys, failing a lot. Meeeeeeeeh. This thing didn't age well.
Also got the Soviet S1-64 scope, analog with nuvistors. Got it for free together with a few power supplies from a tech university robotics association. Might be working - I haven't even fired it up; I'd rather start with an internals checkup, still gotta do that. It goes up to 60MHz which means it'd be the fastest one in my lab, but the size is so OMG it'll stay underneath my bench and work with dummy loads for amplifier testing, and as a fallback device. Plus it has a teeny tiny screen, 6 by 8 cm, not really useful.
Used to have a ZRK OS102, a true beast, clearly inspired by Tektronix. Thing of beauty, joy for ever! All vacuum tube and none of that semiconductor rubbish apart from some diodes and FULL BRIDGE RECTIFIERs. Got it for free from an audio electronics repair shop when they were moving... It served a few years in my lab, but was too bulky for the space I had there, so I sold it. Now I wish to have one again as Tek is out of my reach financially, haha!
Also used to have a Philips 2-channel 20MHz scope but it was pretty flimsy, it broke down at some point and since I still had the Hameg, I didn't even bother repairing it.
Me: Doesn't live in the US, shipping cost more than the scope
Me: :/
I picked up a Tektronix 2446 about 15 years ago from eBay, and I think i remember talking to the seller and the seller threw in a Tek T932A for free... so, 2 for the price of 1! Unfortunately, they both need servicing.
Never could figure out how to setup Ebay Watchlist to that it worked.
Meanwhile, here in Oz, I just got an email notification about a Tek "Tedious" 220, I briefly looked at, which is now going for $A570.48! I wouldn't pay even that many cents! Another delight is a company in Melbourne who have a Tek 7613 like my dead one, that they are asking $A549.99 for. I'm sure I saw a dead TDS series Tek last time for a low price, but it doesn't seem to be there, now.
The problem is, someone as ignorant as I am, needs someone more knowledgeable looking over my shoulder. With new ones there’s great reviews online, not least of all from yourself. Then we can compare specs within a price range and new ones from an authorised dealer come with guarantees.
I‘d take that 54645D any time. Used one at work for a long time and I think a colleague still uses it. Really well thought out interface, a y knob for each channel, what more do you need?
Rather than scanning ebay for old scopes one could look for dave's dumpster for scopes :P With dave getting so many new scopes for teardown review I am sure some of them would be going to the out as well........I am buying tickets to camp out side Daves office....:)
8:30 I have a Hitachi V-212. Lovely bit of kit!
I had an Agilent 54622D which I sold because of not having space for it. I sold it with 4 analog probes plus digital probes pretty cheap (£150) and regret it until today.😢
you just caused all the reasonable scopes to go up, and i cant afford them now, they are over $50 after your video....great job driving the prices up!
It actually is worth your time photographing and listing parts if selling on eBay is your business. Especially If you have 1000's of listings.
Im one of ur fan sir
I lived in phillipines
Ill always wached ur infoemative video
Just a quick hint: You can switch the view with the button in th etop right corner above the search results.
Cool in the TDS380 that's just 45 miles from me, can save on picking it up.
Unless you really look for a scope in the pocket change region I wouldn't go for such old scopes anymore. Getting a 50 year old scope is probably more hassle than it's worth to a beginner, even if it was just for 50 bucks. If you hit the 200$ mark with your shopping you seriously ask yourself if you shouldn't just spend that little bit extra and get a new one instead that probably gives you alot less headache and is a fully features DSO. You can get the entry models of rigol and siglent for around 300 bucks already and you are kind of guaranteed that they work out of the box including probes that haven't been repaired 3 times beause the insulation started disolving 20 years ago..
I bought a £150 Tektronix 2440 so I know they can be bought out there. Sadly this one had a problem with one of the supply lines folding back when the timebase was dropped below a certain range. I've been trying to repair it but could really do with a pointer to an online repair group if there are any out there?
i have modern, but find myself more comfortable using old scopes i run a 2430a which i wouldnt recommend! but also several 2245a and love em ,24 series are far too overpriced and not really available in uk. the key is having one for spares or compare, if you cant locate a fault =swap boards and locate the fault by comparing voltages in the working one , "need a scope to fix a scope"
@@darrenmurphy6251 I have a spare 2440 that I bought as spare/repair. Sadly it's a different Rev and so the main boards are different in layout and so not much good for swapping out. I'll keep persevering with the fault finding, but I may just change the PSU current monitor resistor to overdrive the PSU a bit which hopefully will stop the foldback.
What about those pocket- or DMM-scopes, are those any good? 🤔
Kind of a pain in the ass to use, low sample rate (100kHz range). Might be useful for a few very specific applications.
@Ja Ro They're OK for casual use, and are good enough for relatively simple tasks such as checking clock signals and data lines on old 8-bit computers. Adrian's Digital Basement has reviewed a few of these. Even a "100MHz" (which is really only a 20MHz) pocket scope is better than no scope at all.
@@OzRetrocomp Yeah that sounds like a good use case
id go usb, like an owon vds 1022i, the dmm oned have tiny screens
Lorain Ohio is a 10 min drive from where I live. NUTZ!
Happy Easter 🎉
I think you should adjust for inflation and extend the budget at this point, 5 years is enough to shift prices, especially these 5 years.
I think the crazy over priced items on ebay is not so much somebody dreaming, but it part of a money laundering ring where the buyer and seller know each other and need to get clean money.
Might as well plan another $50 scope video around video #2000! ;)
Oh mate, that is one thing in life that grids my gears, it's so annoying when they just change the format of a well established site🤬 dont fix what isn't broken....
What about getting a modern USB oscilloscope instead? OWIM makes some good ones and having the ability to take a screenshot is awesome.
I got a Hameg 207-3 from 1974 for 25 bucks. 😅
as a noob I've been trying my best to learn how to use it.
Lol those multi thousand $ sales are probably banking on a studio prop department
id prefer one of them dumpster scopes! :P
Yayaya, find me a $50 spec analyzer.. 😊...
ok

Yeah, good luck trying to do that around here, aint gonna work, so often you will find old used ones for higher prices than cheap new new ones... just get them for america you say? Well, then its $400+ shipping plus customs plus taxes, yuck!
going to have to go to How to find a $150 scope on eBay.. inflation amiright?
every time i see a video on a $50 meter i go to look and there over $150
Is it possible to convert a hackrf unit to a 6gig oscilloscope?
Hello EEV blog rookie question are LCD screen scopes safer than tube style CROW’s? I want 20mhz bandwidth but don’t want too much x rays for the bargain.
Zero risk in scope CRT xrays. The usually 2kV voltage is not enough to produce them.
Most CRT scopes operate on voltages well below the ~16 kV required to emit X-rays. X-ray emission was really only an issue with very early color TV sets, and most of the emission came from the HV regulator and rectifier tubes, NOT the CRT.
Thank you for the clarification on the subject. 👍
The sellers on eBay. Listing items with stupid, no hope prices are the equivalent of scammers in my opinion.
I hope they "Only Receive Negative Feedback"
I assume your viewing base is Australia so it would be more appropriate to refer the Ebay Australia. The US market is large but the cost of freight to Australia from the US is off the planet and swamps the cost of any item bought. So maybe focusing on EBay US and excusing yourself saying it is not possible to cover all Ebay counties give more verbal dribble possibility but does not serve your audience needs.
About a year ago, I picked up a new Owon HDS2102S scope-meter for a little over $200 US. You get a 2 ch 100 MHz scope / 4.5 digit cat III TRMS meter / 25 MHz function generator. The batteries are two 18650 cells. This gadget has been an excellent addition to my tool bag and it would make a great first all-purpose instrument for a hobbyist. If one can swing $200, the pay-off is getting a set of instruments which all function to spec rather than putting up with dodgy stuff from eBay.
Wow. Is this common in the US that shipping is that expensive?
eBay lists price in big type and shipping in small type.
If you want $90 you can list the item for $40 plus $50 shipping and some people fall for it.
I find this a reliable way to filter out disreputable sellers.
My view is if you want to get any of those oscilloscopes it is to learn. The spec have 0 importance in this case...
I have Scope meter Voltcraft 707-
I can,t found any data of Scope.
One person is help me of data Scope?
Bandwidh and other data
Looks like I got a bargain with my Gould 465 DSO
HI DAVE. NO REALLY. THANKS ON THIS VIDEO. IVE BEEN TRYING TO GET MOTIVATED TO GET A $150 SCOPE AND I REALLY THANK YOU FOR YOUR LITTKE PEP TALK. YOU HAVE BEEN ONE OF THE MOST SINGLE INFLUENCES ON ME OUT OF EVERYONE. YOU ARE REAL DOWN TO EARTH AND NORMAL AS A THEN COME. A TON MORE THAN WHAT I CAN SAY FOR THE PEOPLE IN CDA IDAHO. ANY HOW. I THINK THAT SPOKANE GUYS TRYING TO GIVE ME THAT SCOPE. AS SPOKANES 17 MILES FROM ME. ANY HOW THANK YOU SO MUCH FOR THE PEP TALK. LIKE I SAID YOU ARE DEFINITELY ME BESTIE
Look at the shipping cost of some of thses so called "bargain" scopes you show. the shipping cost as much or more than the scope. so actually still no $50 scope as it would actually cost $100 or even more. so don't see your point as the shipping is crazy so again, no such thing as a $50 scope anymore. thanks for the video anyways.
eBay Kleinanzeigen is good for bargain finds in Germany
50$ is nothing this days anymore ! the inflation man
If you are incapable of fixing whatever can happen to a scope then don’t buy it. Ive got 50 years in the E business and I bought a “ working “ scope by a bullshit seller. It took me many hours to find parts and fix it. Calibration was another story. Parts ate not readily available , information is sketchy and everyone who can fleece you is just waining fir you to enter their lair. Tektronix scopes are highly complicated using over engineering practices. They are not built for expedient servicing . Thats the analogue scopes too. Forget the digital repairs . A &50 scope is junkyard trash. You are better off looking fir a good TDS 200 digital scope. A working one can be had for $100
in france you definitly wana go leboncoin
eBay US! 😒
In EU you can't find anything even for $150 😅
everytime you make this videos, 50$ scoopes disappear
Well this was a waste of time...
lost me at 50sec..... Fuck ebay us and the postage.
$50 fail lol
50$ is nothing this days anymore ! the inflation man
