This may be a tek oscilloscope that even med couldn't save...



It was found in a pile of trash and listed on CL. The ad said it powered up. The guy listing it just didn't want to see it in a dumpster, so when I offered to see what I could do with it, he gave it to me.  I met him at URS electronics this morning and picked it up.







I don't think I can salvage this one, which is a shame given the very cool coax delay line storage design.  There are rusted pots and most of the pushbutton switches are damaged.







Makes me sad to see gear treated like this.  I guess I will strip this one down for parts, and give the rest of it a decent burial at the ecycle site.




TBH, that I would not have bothered with, not worth the fuel you paid to fetch it home even.  :--

:o I wouldn't even want that on my bench. Something may crawl out of it and bite me.  :scared:

I've had the same thought with some old gear. :scared: :-DD

Man, if med says it is toast, I know I am tiltin' at windmills.  :-DD

I wish there were a way to test some of the boards. I may save them as "give 'em a try if you dare" swap-ins"  In any case, I will strip it in the garage so as not to frighten the gear on my bench.  ;D
.

It might clean up better than you think. I was reading an article in an old Tektronix magazine of some kind a while back about how they disassembled, totally cleaned, reassembled, and returned to service 'scopes belonging to the AEC (before DOE existed) that were contaminated from being in proximity to nuclear testing operations. That's about the worst mess I can think of to have a piece of test equipment contaminated with and successfully cleaned, and back in service.

Should have a few custom TEA bags printed up and include one with the letter;
https://www.goimprints.com/product/custom-tea-bags-550340370/

That's neat. Minimum order is 500 bags ($270). The single unit price is for blank samples, which I assume is for tasting the tea.
I TEA.

I read the two Tek articles on washing equipment and considered giving it a try, after all, what do I have to lose? The problem is it looks like it sat outside in the rain. All of the springs on the push buttons are rusted, as are most of the exposed screws and metal pots. I'd probably have to replace most of the mechanical hardware in addition to whatever fixin' the electronics might need. Not to mention the condition of the case, which would certainly test my limited metalworking skills.

Personally, the challenge for me is not taking this on as a project. The more busted stuff is, the more I generally like it.  ::)

That Bundle Kosmic posted looks worth the drive  ;D Go on do it you are 'retired' and have time >:D

I'm already running out of room and I can't save it all alone.  :-DD

2 hours drive on my side. If I go down there, I'm going to have a fun time explaining to the border officer why my car is full of crap on my way back  :-DD

Could not resist anymore. I had to go down there today. Good thing I have Hatchback. I was able to load everything in the car  :phew:



So the seller of this lot told me he got the equipment with a house he bought (the house was sold with everything that was inside). The house was owed by an old engineer from IBM (The Tek 845 scope has a IBM Tag). Apparently, everything was still plugged-in and setup on his bench when the house was cleaned and emptied last year. I guess he passed away and somehow everything was sold.

I'm both super exited and sad at the same time that the full content of the workbench of someone like me was sold for 150$  :-\

You know, I was thinking the other day about snail mail. How about I send a good ol' greeting card? Since it's impractical to pass one around, if you want to include a short message with your forum name and, optionally, your real one, either

1. PM me your info and message and I'll transcribe it onto the card.
2. If you want to have it in your own handwriting, take a photo of your message and PM me the link. I'll download, print and stick it on the card or, for longer messages, enclose it whole.

Let's say have all PMs sent to me by Saturday, so I have a little time to assemble it to mail out on Monday.

PM sent.

Do I see a Tek 485 and a Power Designs PSU? If so, you have bagged two of my favourite pieces of equipment.

Yep Tek 485 and Power Designs 2005a. With everybody posting about analog scope I wanted want too  ;D

Will post more pictures once I'm done sorting everything.

A 485? Holy crap.....I should have made the trip. Oh well. You scored. :-+ :-+ Mnem...he deserves a jimmy gat or whatever you call it.

I've had the same thought HAPPEN with some old gear. :scared:

And I'm not talking my days in the appliance shop, where you get used to keeping a big spray bottle of Zep within reach whenever you open up a washer or dryer...  I've been bit by centipedes, scorpions and brown recluse. Found a dead black widow in a VCR once... you better believe I jumped back when I flipped that little critter over while brushing out the corner of the case. For hours, every time I closed my eyes I'd see that shiny red hourglass.  :phew:

Of course, none of that compares to my ol' 55 Nomad; it had a nest of yellow jackets that filled half the spare tire compartment, and I didn't discover it until vibration from the motor woke the nest the fist time I started the old beast. I was totally engrossed with finessing the gas pedal to keep it running when I swatted away something buzzing next to my ear.

That hornet picked itself up and stared me down from atop the dash, moving its head the way they do. Then I spied the cloud of wings in the rear view mirror, realized what what going on and bolted like a jackrabbit for the porch across the driveway.  ~~~~~~~~~~~~~> :scared:

The car idled roughly, but kept running for more than half an hour before I choked it to death and pulled a battery terminal.  :o That was the beginning of a beautiful "car and her boy" love story; but that's a tale for another time. ;)

Came across this lovely looking Tek 2430A on an auction site I was going to put an offer down on it then I noticed the rear view  :palm:

I doubt there's any internal damage. It's solid metal across the back.

You can tell it's been out in the weather. The front panel lettering is faded as well as the extensive rust. It's not worth saving except for parts.

Kosmic.......once you get everything sorted I might be interested in that Heathkit 3 inch scope shown on the left in your pix.

That is....if you're willing to sell.  :-DD If you are please post a pix of the outside and inside.  :-+

Yep, I was about to contact you about it. The outside is really in bad shape though. Rust and everything   :-\

Will try to take some close shots tonight.

So in the wee small hours of the morning I brought a bit of TEA gear that will land at over $220 USD and may or may not work and is wired 110V and not our local 240V. To make it worse it only generates one static calibration reference. - What am I?  ;D

And nothing to do with TEA but I gave away my last Bottle Opener so todays production is a dozen more .... :popcorn:

The Heathkit Oscilloscope. It look worst then it is I think. The outside is really dirty. There is rust on the metal part around the screen. Med, if you want it, it's yours. Just cover shipping.

Even came with spare valves  ;) Worthy of a minimal tidy up recap and stuff it on the shelf even if it never gets used I reckon. Patina to spare  ;D

Next time I decide to buy a second hand road case I won't. Several hours later and still several to go  |O

The Scope or the Case or both  ;) Decomposed Foam is a PITA add to that contact type glue of some sort used to hold it in place. The front cover of my 453 was similar but an easier clean.

Multitasking at work while the fixed line internerd has been down all day :rant:.

On a list of 101 thing to do with an inanimate Possum  :horse: and an equally useless $0.01 coin. 4.30pm is testing time.

I didn't see a Scope, so the Case it is.  :-DD [edit] That 1727A I just got came with the little plastic case for the contrast lens thing, and the foam inside is powder.  :palm:

[edit] I now see you were referring to the Heathkit scope above. It does look rather well covered in grime.

Hey - it's not completely useless.  100 of them are still worth a dollar.  You may not be able to use them to buy your lunch - but you can still take them to the bank for full face value!

At an estimated 2 minutes to count 100 of them not to mention time spent going to and waiting at the bank they would need a face value of $0.05 to make minimum wage  ;)
