A close friend of mine of almost 40 years (60 year old retired fireman) from my gym was in terrible excruciating hip pain for many years and walked with a terrible limp. He had both hips replaced at t

This will happen more and more often as we all grow older. We should have a mechanism in place where we can pick up and store these instruments and parts in a facility somewhere. I always wonder what

I used a drop of Kroil on a 7000 plugin knob set screw when it was frozen. That stuff never lets me down. Of course, you need to use it before you strip the screw head! And, you need to be patient - l

Hi Dave, Wow! I thought removing and repairing my 7904's power supply was tough! This really sounds tricky. I'll need to spend a day or so going through the 465 service manual. Thanks for the terrific

OK. Thanks for the heads up. It is mechanical, the coupling switch on the other channel works fine. Best, John

Gentlemen, My 465 has a stuck coupling switch - it developed during a project that I am working on. It's stuck in the AC position. I don't want to force it. I haven't taken the unit apart yet but with

I haven't followed the attachments argument this time around - it comes up once per year and it's always the same questions, answers and end result. But, one issue I found was that the photos in the g

Bob, I found this thread from 2009. https://groups.io/g/TekScopes/topic/7640708?p=Created,,,20,2,0,0. Reed Dickinson posted a formula. Stan also had the paint made up - minimum order quantity is 24 sp

Wow, this Tek blue paint thing has been a problem for decades. I would love to get my hands on a spray can. I'm wondering if the people at Tektronix would be willing to give us the formula? I imagine

I have a Sencore LC-75 - love it! John Justin

Steve, Here is the link to the discussion on using Java SW to copy your NVRAM data using the TDS784C internal floppy: https://www.eevblog.com/forum/testgear/tektronix-tds500600700-nvram-floppy-dump-to

Hi Steve, You need to be concerned with the NVRAM chips - DS1486 clock chip and the DS1650/DS1250. They have internal batteries that hold the calibration constants and options info. The batteries expi

Gents, A few observations. You can pick off the horizontal and vertical analog bipolar voltages on the Display Sensitivity Switching board - diagram 5 in the manual. The same nodes are also available

Hi, Jim. I used many resources and tutorials - YouTube has many good tutorials for beginners. There is Python and there is PYQT5. PYQT5 allows you to build a Graphical User Interface (GUI) easily. - i

I think the voltages need to be picked off before they get to the deflection plates. If you digitize the signals and send them across the serial interface using an Arduino, all you need to do on the P

I was thinking the same thing - he dropped it! JJ

Such a beautiful scope - I have one. Probably just a bad cap in the power supply section! What a waste! What a pinhead! RIP 465! JJ

Great adventure so far Michael. Can't wait for the ending. John Justin

Michael, Congratulations on your 576 fix. I own one myself (purchased 15 yrs ago) and used one back in engineering school some 50 years ago. Great machine - mine still works perfectly! Please, I'd be

This argument about attachments keeps coming up every 6 months or so by new users who can't believe that attachments are disabled. I think Chuck copies and pastes the same old worn out arguments again
