I have a nice 2465B that I bought as being fully restored and recapped (I’ve not opened it up yet but have no reason to doubt) that only has about 460 hours on it. I bought it back at the end of the summer but have only put maybe an hour and a half on it since; I turned it on a couple of days ago and it had a perfect display then suddenly everything disappeared to a diffuse glow off the right side of the screen (UL to photo album "2465B screen issue") After about 5 minutes it snapped back to being correct and stayed that way for another 30 minutes until I turned it off. I turned it on yesterday and it worked perfectly for about 15 minutes then went back to the fuzzies and has not returned to normal yet. Note there is no gradual transition between states, it is as far as I could tell instantaneous. When the display was working it had a perfect, sharp image and passed all self-tests. The problem is obviously (???) in the CRT/display circuitry, but I have not opened it up yet to check anything – I was hoping to find someone that might be more familiar with these units prior to starting.

Any hints and advice are very much welcome.

I've temporarily owned such a system a few years ago. The pictures on Tekwiki show that system. But it's not that easy. On top you'll need a terminal and a compatible signature analyzer. And some components like the signature tables (and maybe the diagnostics ROM) have to be matched to the hardware revision of your 7854.

The diagnostics ROM board also contains some stand-alone diagnostics routines which are helpful for calibration and some digitizing problems.

I've uploaded the involved firmware roms and scans of the manuals to tekwiki. I think the vintageTEK museum is still selling a clone of the diagnostics ROM board.

But in my opinion it's way easier to diagnose the system "by hand".

The SG505 was designed by the founder of Audio Precision, Bruce Hofer. It
is a marvelous signal generator for audio with a THD% level approaching the
level of the SYS2722. For those interested there was an article in Audio
decades ago about a copy-cat version written by Bob Cordell on his website
cordellaudio.com. Jack

Sorry, nothing here like that

I looked for one of these a decade or so ago and didn't find anything.

Thank you for you attention.

Hi Tom,

Don't really remember how I did ut.

I followed a YouTube video where somebody demonstrated how to make round banners in Word, and took it from there.

Sorry,

Leo

Made some progress… I finished the artwork for the SC504 knobs. I am going to have some dry transfers made professionally. Or . Drytransfers.com will do 4”x6” film for $70. Squeeze as many on the 4x6 as you can.

Send-cut-send.com can laser cut the skirts if you need to replace those.

I am also going to do the art work for the SC502 and SC503 and have those printed too.

I let you’ll know how it comes out.

Hi all,

I have created a new photo album called "Tek User Comments". It's for interesting or amusing comments found written in Tek manuals or as graffiti on equipment. I started it off with a "cry from the heart" obviously written by a frustrated technician who had to calibrate a 7T11.

Enjoy!

Any Ideas on how to install TekVisa

Did you try an older version ?
TekVisa v2.03 is part of the TDS5000B Firmware download on Tek's website:

Win2k is supported.

/H?kan

My TDS5034B boots up with a message that TekVisa is not found. After dismissing the message the scope appears to run normally. Tiring of the nag at bootup I decided to find and install TekVisa. The current versions of this software available on the Tektronix site, V4.1.1 and V5.11.1 both state in their prerequisites that my version of OS, Windows 2K, is not listed. I thought that perhaps because Windows7, 8, and 10 were all included that the installation would be allowed. When the install is attempted the screen shows a notification that it is about to be installed and asks for the user to click "Next". The problem is there is no "Next" to click on displayed. I tried an external monitor thinking that maybe it was a resolution issue but there is no "Next" there either. I cannot scroll the screen in any direction. I changed the resolution of the LCD and re-booted. After that I was able to scroll but the "Next" was still not visible so I reverted back to the native resolution. Any Ideas on how to install TekVisa without clicking the "Next" or how to find the button?

Thanks, Ferrous

PS Although there are a lot of bells and whistles on the 5034B I do not like to boot up delay time. I like the color aspects of the display but my TDS460 has slightly better bandwidth, uses standard probes, and powers up faster.

Powerpoint might be a better alternative. It lets you place text at whatever angle you like with whatever font you have installed on your computer.

I recently constructed the graphics for the meter in my Hickok 752A and used Python and the SVG (Scalable Vector Graphics) library to produce the lines, arcs, text, etc. The resulting file can be taken into Inkscape and then output to a file format compatible with Powerpoint. From there, it can printed on whatever media you like. I chose to produce a laser-printed water-slide decal. Kind of a long route to take to get there but it was worth it as trying to recreate all those tiny lines at the correct angle, size, position, etc., would be extremely tedious. The meter looks very nice and the scales are accurate as well.

Leo,
Your artwork looks great. Thanks for posting the Word file you created. I wasn't aware that Word could be used to place the numeral around the circular skirt in that rotational manner. If you can explain a little about the process to do that with Word, I'd really appreciate learning about that.
Cheers,
Tom

Hakan,

Thank you. I must have missed your earlier post. I will make a note to
update the information on the TekWiki site.

That Wiki info is incorrect.

From my previous post (according to manuals and RPR)
154-0838-00 was used only 2213 and 2215.
154-0861-00 was used in 2213A, 2215A, 2235 and 2236.

and 2213/15 have 8kV anode voltage while 2213A/15A have 12kV.

The service manuals for the 2213 and 2213A are on the TekWiki site and call
out the part numbers for the CRTs. They are both 154-0838-00, so they are
the same.

Thanks for the replies, still have no joy on a direct replacement.
So the question still stands:
Will a 2213 crt work in a 2213A?
I realize that the HV lead will need to be adapted.

Hello friends,
I’m looking for the service tools needed for the digital portion my tek 7854: the MicroLab I (067-0892-00), the Diagnostic Test Interface (067-0911-00) and the Diagnostic Memory Board (067-0961-XX).
Interested in hiring as well buying them, for troubleshooting an issue that started recently…
Tnx in advance!
Alberto
