Hi all,
Managed to grab a working (somewhat) benchtop version of one of these scopes, and got it fully operational without cannibalizing my damaged-in-transit rackmount 5223. Was considering parting out the latter but will petition the group for help first.
I need the A2 (Display Adjust/Cal) and A10 (Keyboard) boards (with all pots intact) or the following pots:
311-2042-00 (Qty 1)311-2045-00 (Qty 1)311-1375-00 (Qty 1)311-2046-00 (Qty 2 or 3)
Will also consider a dead 5223 with all boards present.
Any assistance is greatly appreciated.

Ha! Try lifting a 556 up to the bench ;-}}

Why would you add it, when it's not a "Concepts" book? (It's still a
good book, but it should be on a different list.)

The Davmar site has a
complete list with the exception of "Strain Gauge Measurements", which
book I have never seen (and which means my earlier statement about
having all of them is not accurate).

I think that one also predates the "Concepts" series, despite the name.

In the flow lab at my day job we have several rolling hydraulic platforms (200kg capacity, 50cm dia. lift plate) for moving equipment into position; I am thinking one those would be a good investment.

I have considered making something with some steel, acme threaded
rods, a belt drive, and perhaps a place for a portable drill. Not
sure about how to actually build it yet, or if I need something else,
but I do have a 120 pound Weston meter calibrator (which thankfully
does AC volts) that is not going to go anywhere without someone else's
help. The DC stuff, and the 7000 series stuff is light enough that I
can move it without a problem.

There's also the mill and lathe in the shop, and we won't even mention
the 30 inch shear and floor drill press.

So.... I’m finally retiring in September and I’m hefting the 7854, 11401, 577, 547, 570 and 575 out of the basement, yikes! At least there is an elevator.

If you had the room, perhaps you could make an overhead lift out of
some garage door track, some tubular steel, and (if you want) an
electric tow hook.

Might not be a bad idea for those with some of the 500 series scopes,
and far more convenient than an engine hoist.

Harbor freight makes scissors lifts, that with a ramp, might also do a
decent job of lifting a scope.

Great post, wouldn't mind more such stuff on the group.

The Davmar site has a complete list with the exception of "Strain Gauge Measurements", which book I have never seen (and which means my earlier statement about having all of them is not accurate). These sites have live links to those books where a PDF copy exists (on that website) and just an entry in the list for those that don't exist. The K04BB site has an abbreviated list. And one or two of the books had revised printings (e.g., "Semiconductor Device Measurements"). I count 26 total titles, including the aforementioned "Typical Oscilloscope Circuitry".

Also, I think the subject of a complete list of these books has been discussed on this forum before.

I also have a complete set of the Radiation Lab books and a partially-complete set of the Bell Labs series books.

I am not the vendor, I do not know this specific scope, but I do know the vendor - and he too much of a gentleman to advertise it here.

Given that his non-electronic maintenance skills are highly regarded by many people, I would trust his assessment of that scope.

If I wanted a 453, I would be after this one like a shot!

... I've since collected all of the other Tektronix "Concepts" series
of books; ... many of them are available from the TekWiki, DavMar and
K04BB websites (for instance) in PDF form

Uh oh. I guess I will add to my books wanted list! Is there a list of them on any of the sites you
mention?

Well, good news so far! My copy of "Typical Oscilloscope Circuitry" arrived today.

The copy I got via Amazon came two days ago. I’m a happy camper! The revised version I got was published in 1966, the same year I got my BS EE, having used these scopes in labs. I now have a 547 and 545B, so I’m thrilled to have the book that tells about their innards.

Your advice on keeping important stuff off the floor is good. I'm sure, like me, you probably learned that the hard way. My home shop has always been in the basement where it's especially important to keep stuff off the floor.

Jim

Dennis,?
You store it on the floor on blocks, right?? In 40+ years of laboratory work, if I learned one thing is that nothing should ever be on the floor.? There is *always* the chance for a flood.? Basement leaks.? Roof leaks.? Washer /Dryer leaks.? Water heater leaks.? Lab upstairs and next door leaks and the water runs down the stairs....? Everything in my shop that I care about and is there for more than a few days is on blocks, on wheels, or on tables on wheels.? At the very least, I prop stuff on 2x4's.
I'm only 54 and I'm trying desperately to put a personal moratorium on acquiring anything that requires a 2-man lift.? Doesn't always work.
Dan

Hi David,
You're right. I was reading the rackmount weight and didn't realize it.

Yes, I have a 576, it is a bitch to pick up. I end up sliding it on the floor instead. Now that you pointed out it weighs 70lbs (32Kg) I understand why.

My 576 even has the High Current Adaptor which adds another 8 to 10 lbs.

The stand-alone calibrator and its power supply (which I have) add another 15lbs at least.

to.

The catalog says 72lbs, which I think is correct. It has nice big
handles too. For me, it is a lot easier to haul around than a 70lb
576.
