Hey, I have one of these guys in my junque box.. Anybody have a schematic or
documentation of any kind for it? Seems like it worked the last time I used it,
but never had any documentation on it. It's really a pretty nice curve
tracer... might put it back on the bench when I get a small, cheap scope to hook
it to (permanently).

The schematic was originally in the GE transistor handbook. 40 + years ago.

Which edition of the GE transistor handbook was that schematic in? I have a
copy of the 7th edition (ca. 1964), but there's nothing even remotely resembling
a curve tracer in that manual.

Thanks!!!

Jud Williams paid me a visit and was nice enough to leave a curve tracer as
a gift! Many moons ago. He said that he did not "design" his curve tracer
from scratch but did use a schematic from the GE handbook. That's all I
remember. Sorry.
