@Vince: haha, the guy was smoking some illegal stuff with his BMW Tektronix. I think it's rather a BMW Steptronic, which is simply an automatic transmission.
What's ironic is that he spelt Tektronix 100% right, whereas people who ACTUALLY do sell Tek scopes for the life of them are incapable of spelling it correctly ! Even though they just have to write what they see on the instrument... it's too much to ask them, so they spell it in all sorts of weird and wonderful ways but the correct one. It's beyond me.
Quote from: CerebusWhile we're being 'correct' about apostrophes I might point out that an aide is a person who assists whereas a memory technique is spelled aid without the 'e'. You can probably blame the borrowed French "aide-mémoire" for your slip. I would were I you.
That's funny... so looks like this word has not yet fyully morphed into English, you have only partially dropped the ' e ' ! Confusing for sure, I understand the pain it must be.
Here of course no such pain, " aide " is always written this way, be it the verb or the noun no matter if it's a person or an object or whatever...
That should teach you : if you want to use a French word, just use it as is and you will be fine, don't try to simplify/modify it !!!
That's what we do here... whenever we use an English word, we just use it as is, we don't try to French-ize it... We pronounce it in all sorts of weird and ridiculous ways but the correct one, we often don't really know what it means... but at least we don't try to modify its spelling. Well, maybe someone can come up with an exception to that but generally pseaking speaking I would say it holds true !

A 524A, so 2 channels 500MHz, 500MSps, COLOUR screen, which appears to be in good nick too (often they leak, not so this one it seems).
The two channels appear to be working and POST is clear.
Bezel has a crack in the top left corner but not the end of the world, and mostly shows from the side, not from the front, so not a show stopper...
Also supplies two new probes but from what I see on the pics, they are probably the cheap 10 buck china probes, and probably aren't even 500MHz rated, most likely 100MHz I bet, so I would consider the scope as not having probes at all as far as I am concerned.
Only 200 Euros, and well maybe you can negotiate 20 euros off of that who knows.. that would help pay for shipping.
Would happily buy it if I were looking for my first TDS... but I already have two of them now and many more other scopes so... I am not a candidate for this scope any longer, but thought someone here might be...

He is nuts. And willing to spend upwards of $20K to get them shipped to him. Wish I could throw $20K away and not even think about it.
I'm wondering what the underlying reason is for this project. Is it a library for posterity? Is it for some business reason? Does anyone know why he wants to go through this painful exercise?
What about cursing in French Vince? Is it better than English?
And here is what I collected this afternoon, a little Tek scope, the journey down wasn't much fun, very slow on the M6 in Birmingham and completely stationary for about 15 minutes, while a stranded vehicle was removed (apparently).
I thought I would give it a quick test this evening, amazingly it seems to work, needs the two broken controls fixing and the trigger isn't working as good as I think it should be.
Anyone know why these curves show on the CRT, could it be related to the brightness?? Can't turn it down as the control is broken off.
Teardown will have to wait for another day.

I have a newer Type 321A. It does not have those curve marks on the CRT. But I suspect they would go away if you could turn down the brightness.
The Trigger works best in "Auto". If it doesn't lock correctly adjust the Stability trimmer.
The scope is loaded with germanium 2N2207 which are very prone to developing tin whisker shorts.
Quote.....and I don't have a TDR!Note alteration above.
You lot happy now?
Very. TDR is such a cool tech, regardless of medium. I as posted recently finally got round tuits enough to gather all bits and pieces to actually learn the art of OTDR, as executed on our Anritsu at work.Not touching the O variant (sanity and wallet preclude). Besides, the closest thing I have in that type of medium is some cheap filament they use in Christmas trees. Even the digital audio stream I run from my TV to the surround sound system is via copper.

Really ? Normally you don't need to register to contact people on that website, strange.... but well if you say so.
Anyway I can be the middle man to make it easier.
However... as Neper said, maybe I was too quick... maybe this scope is a mistake.... The 500 and 500A series were plagued with the leaky SMD electrolytic caps disease, which corrodes the acquisition board and is a pain to fix if at all possible... My own TDS 544A has already been fixed in this regard, so I know I am safe, but this scope who knows. If it were rotten, it would gives POST errors. This one has a clean POST which is why I got carried away but... now I think of it, IIRC (people ?) there is a way to bypass the POST and make it hide errors... so maybe the seller knows this and is trying to hide the problems.
then maybe not, we just don't know... but yes it's risky.
Well that's easy : if really you are interested, I can message the seller and ask him to open it up and take pics of the boards, this way we can see if the leaky caps are still there. If so yeah... best not to buy it. I can also ask him to make run the self test, teh full suite of them, from the utility menu, and RECORD it in a video clip. If you do that you can't hide the errors.... if he says "sorry I don't know how to make a video with my phone or camera"... then he is probably lying and he knows there are errors !
So just tell me... wanna have me contact the seller to figure it out ?
Todays collection was the other 5245L with the time interval plugin. With rack mount ears but missing the feet.
As you can see it is freshly calibrated by -hp- only 20 years ago! It got a temporary place on my NFM.
Progress with the first 5245L: Replaced all neon bulbs. What a mess. All copper wires were corroded, most have them already were destroyed at one leg.

The 321 manual on Tek wiki mentions the OC170 used in the vertical & timebase circuits, both areas that are functioning, maybe some have already been replaced.

Mentioning the need to re-cap the Fluke 8060A got me wondering about my similar vintage 8021B. How many electrolytics, if any, does it have? So I opened it up and took a look. Two. Both up to the bottom right of the LCD. And verified this via the parts list. Both 22uf/16V. When I do the re-cap of the 8060A I'll do this guy too.
[/URL]
Are you sure there's not more caps hidden under the display? The 8060 has a few there as far as I can remember.
McBryce.
The 8060 is very different from the other meters in the 802[0-9] series, and has lots more bits and bobs. The others are much simpler, and I remember my foray into my 8022 resulting in just 3 "Krusty Kaps" found after a thorough search.

I've seen damaged CRTs before and the trace is usually messed up too, example below from here; https://www.vintage-radio.net/forum/showthread.php?t=106959
Oddly it wasn't seen in the sellers picture, so if it is damaged it must have happened on the journey home.

When using both in the same sentence or paragraph they are almost always linked to the physical proximity of the speaker to the objects in question. If not physical proximity them temporal proximity, with the past being further away and 'this' being the present.
