Here's my copy of the ELV KS7000. It works quite well and has turned out to be a useful tool for the workshop when fixing stuff.

Hooking up devices with clip leads was not only very messy and annoying, it also resulted in nasty oscillations. So I decided to go the
Tektronix route and made up a testfixture. So far I've got this one that works for small & medium power transistors. I've got parts on order to make another one for TO3 packages. This works very well so far.

Certainly no Tek but ok for me.

Besides this, I have the model 3110 from Vu-Data corp., which seems to be a (licensed?) copy of an earlier Huntron model, maybe tre Tracker 1000.

Had the same problem with my DL4JAL curve tracer. :scared:
Fitting a small ferrite bead in the collector line fixed that. :-+

Yes, I did the same inside my fixture. Killed all the nasties instantly.
