Oh yeah ... should we go to the history of hysteria too?
This is phys-l ... at least I thought so :-)

Ze'ev,
my comment carefully did not limit itself to mechanically coupled
systems.
You will recall the experimental studies of female student menstrual
cycle coupling, for example.

Unavoidably easy w/ microphonic tubes. May have been the prob. RP
solved by exchanging tubes.
Yes an e-metronome using, for example, a Wien selected tubed
oscillators, I suspect, would be subject to mechanical coupling.
bc has encountered the prob. in a more modern radio, and made an
e-metronome in the sixties.
