Hi Gerry,

I've posted about "the Andiruptor" on the TCML on Jan 27th, but it 
seems not having triggered the curiosity of the list members. I 
consider it belonging to the "original work" type stuff, which Peter 
Terren was contrasting to the long treads on i.e. "plastic cup 
capacitors". Please see in the archives:

Agreed!

Sorry, probably just _my_ language problem (German-->English). May be 
I should just have written  "resonant frequency" or "mechanical, 
fundamental resonant frequency".
