Where is pic?
I'll show you mine (Tek  575 with pussy on top enjoying the heat, , if you show yours. (Might just show 2 photos offset by eyelength for 3d.)

This one is quite an oscure model (Br 01 from Leybold-Heraeus, made in Germany):



Front panel is mislabeled : read Uc instead of Ub on the right!
I think I will have to do a lot of reverse engineering to get it back to work, as it died the other day...

I made one based upon the infamous "Thai Kit" (https://www.ebay.com/itm/141138017533).
Already talked about it some time ago in this very forum.



This kit is also heavily based upon an ELEKTOR magazine article (Dic. 1989). I made a small modification to the kit to let it switch between 8 and 4 curves and subsequently the total µA/mA. This is a photo of the guts while I was still prototyping it:




It needs a good ole CRO (preferred) with XY mode to show the curves.



The most interesting feature of my build is that it can compare (match) up to 6 transistors/FETs at the same time at the flip of a rotary switch. Here you can see it in action testing some transistors, first with four small transistors (2SC1815) and one power transistor:



The second is showing the details of four small transistor (2SC1815) curves:

This is my vintage Heathkit. It has served me well. The one thing I would change about it is the single ended sweep to bipolar. It does sweep positive and negative, but not continuously. You need change the control settings to sweep the opposite direction. I gave some thought to modifying it, but gave up after realizing I would need to hack on the enclosure to accomplish it.

That's a nice combination of curve tracer and oscilloscope.  Definitely good idea to retain their vintage dignity.   :-+
