[sdiy] Does Source = Drain???

[David Ingebretsen]

I was building the VCO core for my Steiner project and I inadvertently
swapped the drain and source on the JFET. The circuit still worked. I
re-read about JFETS, but didn't find a satisfactory answer. Can the Drain
and Source be swapped in any circuit? That is, are they essentially the same
electrically?

I bought a Peak, Atlas DCA semiconductor analyzer, and it can't distinguish
from the source and drain either.
