I made a post earlier about a mystery cable coming from the A4 board in my 2465B. but the more I look into it, the more I am puzzled about the A4 board in this scope. I can't find any photo or manual

Hello all, I have probably developed cancer. I can't get in for treatment. I have enough lumps in my body that it probably wouldn't make a difference. So more than likely I am dying. I am asking for e

Ok, here we go! Now I'm in it. Took the trigger/sweep boards out yesterday, no problem. I'm trained and somewhat practiced at solder work, so that in itself doesn't bother me. I was a little intimidat

I have seen that the Tektronix 2335 was available with “Option 03”. This provided a switch for 100V/200V nominal input voltage. The chart on the rear of the scope shows the range; for 100V, it is show

From Tim P (UK) Just got back into my quest for a working 5441 - I've given up on the instrument with the 'howling CRT' and bad storage board; that one had the fault where it would fade positive in NO

Hello all, I just joined yesterday after looking for a good forum group to connect with regarding my rekindled interest in Tektronix oscilloscopes. My history with these scopes goes back to my Army da

*Many thanks for all the replies from members. * *I checked the pins to make sure that they were soldered and even re-soldered them carefully.* *I know it all depends on what kind of open there is and

I recently purchased a Type 515A oscilloscope online, and noticed that it’s labelled “Type 515A-S1”. After some investigation I found that the “-S1” means that it can run on voltages of up to 800 cycl

I have two broken Tektronix 465s and one 2336 that I want to give away for the cost of shipping. Anyone interest in one or both? Pete

Hi, Are there many Tek units that use multi-section electrolytic capacitors? I came across this company that have a range of new caps available and can make custom orders, I've not used them but would

Need some basic clarifications and guidance. I want to view some wave forms of a 465M scope with a 460A digital scope. The manual for the 465M tells you to run a 50 Ohm cable between the "A EXT Trigge

Hello all, I forgot to put in that I live in Reedsburg, WI 53959 which is near the WI Dells. Sorry about that! GOD Bless and Thanks, rich!

*I wonder if anyone has tried a large capacitor and high voltage to weld an open filament in a CRT?* *And how did it work out? Supposedly a cap with 2 or 3 hundred mfd and a high voltage to create an

What do you mean by "getting Tekscopes"? If you are hoping to become a member of the Forum, you need to write a sort-of resume/justification and send it to the Moderator. If you mean buying Tektronix

I have a 475 that belonged to my father, manufactured in late 1974, that I have a sentimental attachment to and would like to keep running. To this end I have purchased several "for parts" scopes on e

In 2017 when I bought my copy of Peter Keller's definitive book on the CRT I paid $70 for it. 1) PETER WAS VERY CLEAR: HE HAS NOT GIVEN ANYONE PERMISSION TO SCAN HIS BOOK OR TURN IT INTO AN ELECTRONIC

Dear Tekkers, Over the past two months or so, I've been working on a [Java] GUI for my Tek2440 accessed through a ProLogix GPIB-ETH . Since I still do not know all the Tek2440's features that well, I'

For several decades, Tektronix has released these "Technical Briefs:" a.k.a. Technical Documents, Application Notes, and possibly other names. Is there a single point(s) of curation for them?
