Tim, I parted out a several Tek 7000-series plug ins. They were mechanically damaged, so I pulled parts. Among them are plug-in attenuators. I have several, but of the ones you mention, I have: 307-10

Another possible cause of the backplane connector shield failure - shipping a 5000 or 7000 series scope with the plug-ins installed. I believe that Tek never shipped scopes like this and advised anyon

Colin and David, If you look at eBay item: 133386313435 it is the plug-in backplane for a 7854. In the fourth photo, I believe it shows one of the connectors that is missing the cover on one side of t

Rich, Thanks! I’ve been pretty fortunate and these are the first dipped tantalum caps I have had fail like this. Steve H. wrote:

I had two dipped tantalum caps fail pretty spectacularly (loud pop, smoke) in a 7B53A. Those who replace these, what do you replace them with? Just newer dipped tantalum caps or a cased tantalum cap?

Some additional information from the earlier Tek group. The letter is manufacturing location, but here are some other letters besides “B”: The first digit if there is no letter is the location of manu

There was an explanation in the older Tek group about Tek serial numbers. There is (or was) no correlation with manufacturing date. Apparently, the “B” stands for “Beaverton” (where made). The two dig

Bill, I have seen a transition. I work at a major academic medical center. They used to have a policy of letting employees take home computers that were working but out of their current specifications

A short aside first: Jeff - I believe we used to attend the same hamfests - at least the East coast ones (esp Gaithersburg). Often with the late Bill Scripps. Contact me off list if you’d like some up

If you are looking for a 2465 of any vintage, I suggest checking out the seller “2465b” on eBay. I have no financial connection with the seller, but I have bought items from him. He supplies them full

I don't have anything to do a side-by-side, but Tek blue looks like "Federal Blue". Has anyone compared them?

Years ago, I was able to buy a can of Tektronix blue paint from Tektronix parts. I presume that the option is long gone. I suggest looking through Pantone colors as these are standard and many paints

Jean-Paul, Yes - I am a radiologist, though now semi-retired. My specialty uses a lot of high-voltage equipment. X-ray generators put out 120kV or more and at sufficient current to kill you, so I leav

This article on the Web has very good explanations of the parts, their use, and safety considerations: https://www.teslacoildesign.com/construction.html Sorry if you've already seen this. Best of luck

For precision CRTs, it's hard to beat the high-resolution CRTs made for film recorders in the days before laser light sources for these. Film recorders made by Celco were used to convert digital imagi

Eric, Sorry for the second message. I checked the part number on TekWiki and it is the 7000 series blank panel. Steve

Eric, I have a blank plate - I am fairly sure it is for the 7000 series mainframes. Tektronix part number 016-0155-00. It has a black plastic plate on the back that projects back (into the plug-in spa

I believe I have one. I will check when I get home and let you know. Steve

My interest in restoration of electronics stuff is mostly frequency/time standards. The ones I work on are from the ‘60s and later. Most have discrete components. These are mostly ovenized quartz osci

Those who have been posting about replacement Tek CRTs, you may know of the Sphere Research "Stuff Day" sale. Walt Shawlee has Tek CRTs available both used and new. Here's the URL: https://mail.google
