Freecad is getting much better than 10 yrs ago. Stretchable parametric models work well until you get nested levels about 4 deep, then it could hit a snag. Freecad devs compile it for windows 7 and la

Well that counters the OP's worry of tool and design flow disappearing, but going commercial paid is a similar problem for many non-specialists, retired and self employed. In those cases, open source

Hey! Enjoyed seeing your video!

Thanks for posting this!

I have a 7844 that sort of works. The mode switches are intermittent -- odd level shifts or opens happen when pushing the buttons. The board that contains vert and horiz switches and vert, horiz separ

Do all of the FET 1A1's have four-sided V/cm knobs?

Sure, and those old carbon comp R's are drifted away from 50 Ohms now anyway... Not saying to go different type of R, since Carbon comp are good RF R's, just select for good value, or maybe bake some.

One of these turned up and I wonder what the 104F mod is. Anyone? https://www.ecosensory.com/tek/556-scope-serial-numbers-3.jpg

I saw some of those tube harvesters while picking up today. They are just business-like about it. I saw one get a custom circuit with giant power amp tubes in 2 rows of 12. He'll probably plug them in

There is not much early interest in these, so probably going to tube harvesters. https://www.bentleysauction.com/auctions/7544-1642-NM-Surplus-to-the-Ongoing-Needs-of-Pulse-Power-Physics-Online-Auctio

Do you know the differences between DSA602A and DSA602? Only DSA602s for sale here... Thanks for the reviews. I'm probably going to get both also. 500 W is a surprise, but since I'm no longer in Texas

What are your favorite features? Can you set it easily for 14 bit resolution so the lower frequency traces have detail? How is that done? Menus? What's in that big box? Are fans loud?

I could get a a couple of these cheap locally, (one for parts), except they are not super repairable...and they are huge. Anyone like their function? Skip to 11801 or CSA803? John

I miss your input.

I have a parts box from a RM504 that may help, and some ceramic caps from Sandia lab that are all arranged neatly in Akro Mills organizers that could be a source also. The other way to go is take SMT

I got a bounce trying to send to one who requested, so I put a zip file of the Gerbers on my server. I run my own mail server and it occasionally gets blacklisted by some ISPs. If you want the pcb-rnd

I sold out and have not reordered parts. Yes, RS-274X and pcb-rnd files are available -- I'll send you a zip of the project dir. It's just a straight through, so no schematic.

+1 the mounting can just be a shelf, and maybe some sawn plastic or wood holder for the camera to keep it square with the shelf and scope. The digital cameras I have take a while to turn on and get se
