that may be a collision ib my hash tables.
Isn't that a magnetically-induced thing related to crystal
dislocations under a changing magnetic field? i.e., Barkhausen
noise.
I also think of early HF oscillators produced by placing the grid of
a triode at a positive potential relative to the cathode and the
plate at a negative potential. Called "Barkhausen" or "electron
orbit" oscillators.
Also related are oddball oscillations in tetrode HF power amplifiers,
I think.
Or it could be the Thanksgiving Day (today in the US) liquor
talking...
