Test Equipment Anonymous (TEA) group therapy thread

[tggzzz]

The word salad is good with those, how can it decide "perfect for anyone in need of reliable test equipment" is appropriate for items listed as "for parts or not working"?  To be honest there is nothing to show that the one that powers up is actually working either, not that I would be interested either way.

That is generative AI at work. Not sure who would be liable, ebay or seller, if a dispute ever came to court.
Athe price is OK'sh for a pair of 8060As. I know the IBM ones seem to carry a premium in the USA. Never seen one in the UK before.

The seller would be responsible for whatever they put in their sales literature.

Similarly a car driver is responsible even if they have swallowed Tesla stories about full self driving (beta) cars.

From experience I know not to buy something that looks a dogs dinner just because of a name (unless the price is low), if I wanted an IBM one I would wait for a decent condition one to turn up, I've no problem importing stuff now, as I've started using shipito.

Here is what I think of flawed A.I. generated crap by ePay. 



P.S. I still haven't done anything with the Fluke 8050A that I took the Ni-Cruds out of, I was told the display was bad by the previous owner.

P.S. Maybe you should sell it.

Alright, I need some serious input on this one 
https://www.ebay.com/itm/356204034380
Tek MSO46. Looks like it was dragged behind a car and hit in the front and rear by a jealous Ex that listened to too much Carrie Underwood 







I threw in my offer and in a short amount of time it was declined. $500 USD is dang generous for an instrument in this shape. 



After looking over the Tek service manual, I think there's a chance it might be fixable. Sadly, looking through Tektronix service documentation, nearly every part is not available for purchase and requires the scope to be sent in. I don't see how an LCD replacement requires virgin cotton white-glove tektronix approved repair.   




The rear set of ports is on a daughter board and the rear does not look that deformed near the high density amphenol / samtec connector. There's a good chance it's just the rear external trigger BNC's are damaged. The front BNCs may bend back into shape with some tender love and care.



I sure would give it a good home.

With that amount of impact damage, I'd be worried about internal damage to the PCB's and board-board connectors and such.

Absolutely. We are talking about a slim chance for repair here, but with risk comes reward

With that amount of damage, NFW I'd pay more than 20 quid for it..
Far too high a chance on say hairline cracks in the multilayer PCBs or damage to soldering,loose BGA, what have you. The proposed price is insane.

He says it powered on but the display doesn't come on (d'uh). It has HDMI on the back. Given the other stuff he's selling is very much in the same wheelhouse I give it a 90% chance he tried the HDMI and got nada.

Yep.  Edelschrott.

I'd hazard a guess it was sent, repacked & destroyed™ by the ePay Global Shipping Programme.

Selling it would be bad form, as it was free from another forum member (not on here).

Look guys, all the BNC's are crushed!

I see it all the time when I look at yahoo auctions in Japan.
some people put hundreds of dollars into TEs that are on the verge of destruction.
as long as the pcb is not damaged, I think it can be fixed, but I don't like it if I can't get cosmetic parts.

By the way, does anyone know of a tool I've seen before that corrects crushed BNCs?

[Ice-Tea]

Marconi 2305. They don't go for much but are actually nice. Serves as a 2G frequency counter as well, that alone is worth the price of admission...



This one doesn't boot. Might have something to do with the missing masking tape on the ROMs. Sticker glue residue is still there but some ass removed the tape. Not sure if that's enough to corrupt the contents as there won't be much light inside the unit but maybe over time?



Don't much like the abundance of Philips radials. This cap doesn't look great either but it's in the analog section so it won't have anything to do with the boot hang.

Yes, a soldering iron. If they are fubared like these I would not even think about trying to fix them. Replacing is the option of choice.

Now that is a rats nest.. wow. Serviceability was not high on Marconi's requirements list it seems.

[Robert763]

On the Tek scope.
It clearly has been deliberatly damaged, De-Milled, Widlarised, call it what you like. They have done a through job.
Don't touch it with a barge pole.

...sometime ago (about 30 years) I got three ex NATO Dawe CT439 AF signal generators - one of which may be getting taken apart soon.


I guess it's now the right time to have a look inside.



not so much info about it - and others have asked on other forums, I see

Well the Fluke 8050A was exactly as advertised, the LCD is dying, but not quite as bad as the Danameter, when off it looks perfect, I'm thinking all these older LCD are going to start failing sooner or later.



To test it I connected a 6V supply to where the battery leads used to go to, all the functions seem to work. Should be able to try one of the many replacement ideas in the future.

Have you tried asking here? https://www.vintage-radio.net/forum/

There is info on some other Dawe oscillators (which are hollow state), but no-one has asked about the CT439.

Good old AH supplies. I bought one of the Cossor CME 110 "cable testers". Actually an early portable TDR. It worked really well. There was one on ebay a few weeks ago but I resisted....

[Robert763]

Talking of old surplus suppliers, I was a Customer of "Johns Radio" in Yorkshire for many years. The company faded away at the turn of the century pretty much without trace. A search tonight revealed that John (John Heeley Townend) died in September 2023. His family is still running the mill where he was last based as a commercial property.

Not overly sure I did get my three CT439s from A H Supplies - definitely from a surplus type premises in Sheffield, in Kelham Island I think. The Sheffield link may be a coincidence.

I just love this attention to detail when it comes to serviceability.
