Just joined as I inherited a Tek 485 in operational condition. I'm looking for a cover, Tek part number 200-1251-00.

My first exposure to Tek equipment was in high school, we had several model 502? (It's been 40+ years). Then to
NASA / JPL where we had hundreds of various models.... Always loved Tek gear.

Those covers are pretty hard to find. Great oscilloscope you have there though. Welcome to TekScopes

Welcome!  My first real scope was a Tek 502; I started repairing it when I joined years ago, but never completed the repair- too many better scopes to play with.  One of these days...

Hi,

I too am interested in a cover as my 2245A came without one. However as I got the 'scope at a bargain price (I think) I'm on the lookout for an inexpensive cover. Which is to say on that's not 20% of what I paid for the scope.

My point of posting is really to ask if 3D printing would be a viable and relatively inexpensive way forward? Or is this too an expensive option. I have already had a bit of a poke about in the places suggested for 3D print files for feet and knobs and didn't find any covers.

As a neophyte to 3D printing it would seem that a cover is a classic case for a parametric design with width, height, depth, and corner radius being all the parameters that would be needed for a generic replacement cover.

Cheers, Brian.

 

Welcome WA6ILQ,
Plan to finally get around to doing my Tech and Gen HAM exams.
Always gazed at adverts for Tek scopes etc. in Radio Electronics mags from the late 70s & 80s. Could never buy one until some second hand 2465 & 2465A units a few years ago. Plus I also have a couple TM503s and about 9 plugins targeting calibration of those scopes.

Sadly, I don't use those fine analog scopes atm, as my lab space is so congested I need the compact (Rigol 300Mhz) digital units. My biggest Bandwidth scope is a 3Ghz Tek TDS694C in good cal.
Haven't done up new project write ups lately either as I had major surgery near Christmas last year with a 2 week to brain death encephalitis scenario driven by a 'silent' stage 2 cancer tumour.

Well, I'm still here to be an active part of the group. BTW, the neurologist found my cognitive brain healing (measured & documented by EEGs and MRis) has exceeded normal expectations....probably due to the technical work we all do, so I have documented evidence that our work/hobbies keep brain synapses and axions strong.

Welcome Again...

Such a cover could be printed, however, It would require a large format 3D Printer (which most do not have) to print as one piece or the model could be broken down into two or three pieces, printed on a smaller machine, then glued together to form the complete cover. This might not be an issue for some and the seams could be somewhat hidden. Keep in mind that 3D printing does not deliver exceptional surface finish on these less expensive machines, so don;t expect the resulting print to be anything like an injection molded part.

Michael, thanks for your thoughts and insight.

Brian,

Trust me, I have toyed with the idea of printing a front cover for my 465B and 475A. I just cannot push myself to pay $75-100 for an original front cover which I will hardly ever use. If I get up the nerve to try it, I will post on this forum with the results.

Hi all,

The real sadness of the matter is, these front covers probably all ended in some deskdrawer to keep pencils in...

So, if anybody has a cover for a 2465B, 2465ADM, a 475A or a 485, let me know.... :-)

BTW, do covers for a TDS540B exist?
If so, I want one of these as well....

Good luck on our mission,

Leo

I recall using them at Halted, Haltek and Allied in which place parts as you wandered around the store. I am certain they were later tossed....thinking back I feel bad as I did not know what I had in my hands! I too am looking for one for a 475. However, a cloth hung over the front seems to to just fine for the one on the bench.
maybe the "feng shei" will supply everyone who needs one.

I loved Haltek!  Halted not so much; I never even made it to the new Santa Clara location before they closed for good.

Dave- so did I, my dad took me over and while he was looking something....I was spelunking in and behind the "stacks of stuff"! that started my down fall into electronics ................later I still went just to see the good stuff! oh and get parts, stuff and things! I still have a lot of the stuff and things!!!
one can never have too much stuff or things, one never knows when it will be needed! LOL

If I wanted a cover to protect the controls, then I would make one out of ply using a laser cutter.

It would not look the same, but would be functional.
