Transistor testing board

Hello,

I was wondering if anyone knew of a etchable layout for a germanium testing rig?  Based on R.G. Keen's rig - this guy would have a socket for a transistor and the appropriate other sections.

What do you guys use for testing?

$70!  Yikes!  That is fancy and all but I was thinking something that I could etch based on R.G. Keen's schematic here:

Perhaps even with my mediocre Eagle skills, I can make something.

Certainly, but if you're doing a lot of trannies the dc55 is the way to go.  Much faster to get the gains and leakage.  Plus it gives you the pinouts.  Especially helpful on some stuff you cant find the datasheet on.

Why not? That is a very small, doable circuit. It's doing those kinds of things that will sharpen your EAGLE skills. 2 resistors, a socket, a switch, a battery, and two pads for the DMM lines. Go for it!
