Useful devices

I'm planning on combining the testing devices I've built into a single unit. So far I have
Opamp tester (http://music-electronics-forum.com/atta ... iagram.png)
RG's JFET Matcher (http://www.geofex.com/Article_Folders/f ... tmatch.htm)
RG's Transistor tester (http://www.geofex.com/Article_Folders/ffselect.htm)

Are there any other things like this which anyone has built or know of which might be useful?

I really like the transistor tester on the bottom of this page, great for sorting out dodgy germaniums http://www.aronnelson.com/gallery/main. ... ewsIndex=1

The Opamp tester schematic is nota vailable for non members, ¿maybe you could redraw it and put it here?
