[Milsurplus] Vibrator Replacement

[David Stinson]

Does someone remember the simple, cross-connected
circuit with two transistors and a couple of resistors
people commonly use to replace vibrators?  
The primary-only type, not the self-rectifiying.
I can't remember what I did with it.  Online, I've found the
silly, "three ICs and 27 other parts" nonsense and am
not interested.  Simple works fine.  I just don't want to
trust my memory or rip-open one I've already built 
ten years ago.  Thanks.
