Looking for front cover for 465 and/or 485
|
485 covers don¡¯t have part numbers embossed on them. You have to measure the dimensions of the metal rim around the ¡®scope panel and look for a cover that has those dimensions on the inside of the cover.

Most covers were separated from their ¡®scope when the company that bought the ¡®scope started using it. When the ¡®scope was retired, the cover remained in a cabinet or whatever and was later tossed because there was no associated ¡®scope with it (or, for all I know there are thousands of ¡®scope covers still sitting in cablnets all over the world).

Isn't the 485 a bit like the 453, in that the cover is made of metal and is held in place by catches on either side? The other 400-series scopes have a plastic cover that just clicks into place. There are two types of plastic cover, one which is fairly plain and simple and the other which has the "penthouse" extension. The "penthouse" extension is used with scopes that have an attached DMM and with the 468, which has the extra circuitry on top for the digital memory.

The cover for the 485 is similar to those that fit the 465 and 485 (I know because I owned a 485 with a cover). That is, plastic, no catches other than a molded clip on either side that snaps over the ¡®scope¡¯s outer rim. It¡¯s outer dimensions are, of course, different than the 465 and 475 covers.

I have never seen a 485 with a DMM option. DaveD On Aug 17, 2020, at 12:54, Colin Herbert via groups.io <colingherbert@...> wrote: |

I wonder if Tek had made the covers for the 400-series scopes more like the one for the 465M, where there's a somewhat useful storage compartment built-in, whether the covers would have stayed with the scopes better over time.

I think many people consider the covers as shipping material and don't take care of them later unless the scope is used as a portable. A scope sitting on a bench would be sold off later, the cover was "somewhere around here", and got thrown out later once the scope was long gone. For any military test gear from about fifty years ago, covers were deliberately tossed or taken/sent home if possible. The first-term enlisted (often draftee) techies didn't want to deal with keeping everything in inspection order. Once the equipment started coming out as surplus, or slipped through the supply system cracks, they had the covers and rarely used accessories to make a nice instrument for themselves at home. We restore and treasure the TEK gear we have now, but a good portion of it was used in a daily, down and dirty get-it-done environment. As long as it was working well enough to get the particular job done, little else mattered. With the fast obselescence of a lot of communications and industrial equipment, longevity of test gear was not a great concern, and mangement considered the Carbon Unit cost too high to justify anything more than the minimum time needed to keep it functional. That is very different from a lab, broadcast station, or post-Vietnam war military environment. That's my real experience!

I've considered making custom covers from laser-cut birch ply.

That should be trivial given the ability to generate finger joints, e.g. (no recommendation, simply the first I googled) On 20/08/20 07:07, dabono@... wrote:
Here's an interesting one - custom-made from clear acrylic. IMO it's a bit expensive ($85), about what you'd pay for an original Tektronix front cover. |

Yes... I mean go for it, if its a project you want to do... but, it's not the same really... is it?
I reckon, most Tek scope covers go missing because people don't need the cover. And I second reckon, most people who want a bonafide Tek scope cover...well... they want the veritable cover not because they need it; but just because, they want it. Like the famous (and now the very rich) have often lyrically opined... at far too many decibels too (as I now unfortunately know,) "You don't always get what you want. But if you try sometimes, you get what you need!" |

I use plastic bags on ¡®scopes for which I don¡¯t have a Tektronix cover. DaveD |

on my shelf I have a towel to use as a dust cover.. (works on all my stuff to keep the dust off), for the portable scopes I am fortunate to have a ( one) cover for my 475....I obtained it at a surplus electronics house using them as parts bins!.....had I known that in the future they would be so desired....I would have absconded ( i think it was a $1 USA) with all of them for later distribution....
