I Love tektronix

Mr. Wizard: "Don't move!" Kid: "Here we f'ing go again with this crap!"

Oh my! Well, that was almost unwatchable! I think they let Junior loose on the edit machine! I've never seen something so poorly edited before!

I own a 2445A. Very useful video!

My Tektronix 2465 is just a great scope. It is 300 MHz scope , yet I can still display and measure a frequency up to 1 GHz. It has the Options 06 and 09 which just adds to its usefullness.

I still have my 2467B I use it on my bench to repair audio gear. What a great scope!

I have a fully restored and calibrated 2465BDV on a K212 cart FROM Tektronix themselves. I am embarrassed to say I did NOT know about the 5 divisions measurement. Time to read the manual! Again..... I absolutely LOVE these videos, please keep posting them to preserve their history. I still repair analog audio and video gear with my 2465BDV. Still quite the scope, even today.

I still have my 2467BHD on a Model-3 cart. Youngsters might never know about the secrets hidden in analog waveforms. I still repair CRT monitors with mine.

Feels like the retro encabulator

Vacuum tube is filled with pure Devine Spirit...so that it is having a magical attachment to humans. Vacuum tubes have a spiritual effect. I love that

When was this film made? There's literally nothing to indicate its actual age anywhere...

The Tek 7000 was one of the most perfectly designed scientific instrument series in the history of humanity. The only omission was not putting the rated upper bandwidth of the plug-ins on their faceplates. Input impedance and capacitive loading ARE stated on verticals.. I am adding a small label to all my 7000 components indicating the upper rated bandwidth. With multiple mainframes and well over a dozen plug-ins, its handy to have BW stated.

Great story sir. Thank u for taking us inside mfg labs. Jussojuan

Cool recording, thanks for posting this.

Very hi-res for the day, i'm sure

Incredible. This is all now a cots server running software analyzing packets.

This is when they started spying.

Wow. That intro, fantastic.

Sweet. So needed now to show this to young people. So they will know what basic laboratory instruments are for. I so sad, that these materials are no longer on popular media. When I started with DIY Moog synthesizer modules - oscilloscope provided great help with starting and initial setup of that modules. This was digital one, but with proper fluorescent tube display. Perfect tool for it. Specially for oscillators, filters, LFO and slew limiters. I could watch how they work and how good this work is.

"Even Hoby workbenches" 🤣

Nice hair. Wish I had it.

I'm planning to create an EE club for my highschool, and this video will definitely be on my list of things to show in that club! I have a couple 2200 series scopes as shown in that video so even better! Thanks for providing this film!

This is great! I love these sorts of informational videos from the past!

Oscillowhat?

I got that exact model Oscilloscope right after High School. I was SOOOOO PROUD!!!!!! 🤩

...and yet Tek never made any inroads into PC graphics cards. They saw it coming and couldn't do it. Neither could any of the other "workstation" level graphics companies, not even SGI.

Riddim

Hard to believe this entire field was made obsolete almost overnight by LCD.

Isn't it nice when all the semi's are socketed, well unless the sockets are corroded.

You see how the vacuum in the crt just sucks the glass in when the tube breaks

Great oscilloscopes! I restored a 545A.

The old style wet tantalum capacitors usually have a sulphuric acid electrolyte, make sure to neutralise any leakage with a water and baking soda paste.

Great stuff here!

I think it is about the volume of manufacture. There is still something like this happening and I am glad being part of it. I am talking of dilution cryostats. Welding, brazing, sintering, electroplating. Done in-house in small batches. There must be other products too, but only small scale. The pressure gauges we use say "made in Lichtenstein" 😅

I fixed a couple of PS501's and found one had an open circuit main filter cap and the other had a dead (open) current limit LED. As the LED itself is part of the feedback path, this caused it to have no current limit at all and I ended up killing the pass transistor in the mainframe.(replaced the LED's with brighter 1980's ones) I also have problems with intermittent operation of the output PBT switches on both units & with similar switches on the DM501's I have.

Concise analysis of the failure, its potential causes, and possible remediations. Very well done.

Is there a suitable (modern) replacement for the 741 that has a higher maximum supply voltage? OPA551 maybe? It strikes me that the choice of OpAmps may have been more limited back when these modules were designed and the 741 was chosen. I sometimes wonder if the choosing of the 741 is willful or just "that'll do".

Great info! Tnx for your efforts!!

We had two of these at U of P when I was there.

I don't know about Bldg 13, but I do know Bldg 50 had significant asbestos issues even into the 90s. If work above the drop ceiling was happening, everyone had to go home. That would explain the mask precautions.

I worked on such a machine as an intern in 1979. The system was complemented by a file manager (8 inch floppy drive) and a plotter, all connected via GPIB. The performance and of course the graphics capabilities were amazing. I still have some listings and plots from these days.

Can you play 'Artillery' on it?... KABLOOIE!

Fantastisc, Very satisfying to watch

Wow! I think the 611 was the series of storage tubes used in the 4051 and 4052! I loved my 4051 in my first job after university - it was my first personal computer experience! When I tried to find one in 2000 - I found a 4052, then found a 19-inch 4054. I love both of them and am still creating new BASIC programs for them!

You might be interested in this UA-cam video. It is part 1 of a very detailed restoration of a 576 curve tracer. ua-cam.com/video/pQRmlUGJsZA/v-deo.html

Hi Bob, Just finished looking at the video of the 5-volt supply. My 468 had failed about a month ago and I finally got around to check it out the other day. The problem was exactly the same. The Shotkey diode was shorted. Luckily the crowbar transistor was still okay. I replaced the diode and the capacitor next to the diode because it was leaky. Now the 468 is up and running again. Good video on replacing the diode and troubleshooting the problem. Don

Awesome film, it made me want to recreate the campus in both cities Skyline, and minecraft so that it will never be lost to time

I have a problem with the 4x attenuator on one channel. Not sure if it is the attenuator or the board at that location. I should swap the 4x on each channel and see if the problem moves. Then I will know if it is the board or the attenuator.

lovely vintage porn .............. could watch this all day ........none of us could afford these back in the day, but i did repair a 7603 with 7b53a . and 27a18

👌👍
