I once ran into a former Tek employee at a hamfest where I was looking over one of the 500-series scopes. He said that in the day when Tek serviced them, they washed them with water and then warm-air

Albert, Thanks! That was it! I have never seen another one of these. Steve

I have a number of 7000-series plug-ins of varying ages. The intensity of the colors (silk screened? anodized?) definitely varies, but not always "oldest are most faded". I suspect it has to do with l

Dave, Since fluorescent lamps use mercury vapor to generate UV which then excites the phosphor lining the tube, they do produce some UV output as the phosphor absorbs and converts most of it. The IV o

Walter, Please advise me of when the "stuff day" is to take place and when you post listings of what stuff is up for sale. I can't make the trip, but I will consider bidding online. Regards, Steve Hor

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

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

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

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

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

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

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

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

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

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

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

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

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

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
