New (From 1965) Tektronix Oscilloscope

Some of you know that I go to some of our local e-Recycling centers now and then to scavenge what I can find. So far I have gotten many laptops/notebooks/netbooks, several tablets, many power supplies, and lots of other little treats.

This is one of my newest prizes:

This is the same model as the ones that Marilyn, and I, used while in the Air Force. It actually has a lot of sentimental meaning to me because of that. Marilyn remembers using them, although she's not too keen on getting back into playing with them.

This one was in the recycling place, set apart by itself - not with all the other junk, so I figured that it was being left there somewhat reluctantly. I hoped that it would work, and when I plugged it in (and stumbled around a bit looking for the right controls) and turned it on, I was pleased (giddy, I told Marilyn  ) about getting it to work. If you look closely, you may be able to see that when connected to the 1KHz test signal, it shows 2 squares wavelength (on .5 ms per square,) and 2 squares peak-to-peak (on .5 V per square.) In other words it passes the first test for calibration. It appears that this was kept in pretty good shape (calibrated regularly) and only put away when it got replaced, or maybe "Grandpa" passed away, and the (grand)-kids didn't recognize the treasure that he left for them. Their loss is my gain.

Very nice find! I once completed a Heathkit Scope. It lasted about a year before it died and parts (tubes) were not available.

Another 'scope that I own is an old Heathkit IO-12. It is so old that it does not have any grid on the screen - it is not meant to measure anything, just to show the shape of the waveform. Unfortunately, it never worked, and I have not been able to get it fixed.

Do you have the documentation for it? I was fortunate to have that with mine, making troubleshooting and completing it much easier. Sadly, parts became the final issue. But it was technically my second scope. My first "scope" was really a 10x10 LED matrix, experimental "scope" designed by Forrest M. Mims III and published in one of the may Radio Shack Engineering Notebooks I had. You could display simple waveforms, which was something.

I do have the documentation, including the Service Manual and a few YT videos. I just gave up on trying to fix it when I came up with (don't remember where) an HP1722A, very nice scope. Then Jason, from the old S///C forum took pity on me and sent me a REALLY nice Rigol DS1102E. I've used that more than all the rest combined (well, more than the HP, since the Heathkit never worked, and I just got the Tek.  Although I did use the same model Tek in the Air Force, way more than all the 'scoping that I've done since I got out.)
