[Milsurplus] vibrator power transformers

[Christian Fandt]

So true Richard. Why switch the cap in/out?? (unless person was 
experimenting only)

What I've been hunting for are circuits and discussions on solid-state 
vibrators. Anyone know of anything and can point us to such info on the 'Net?

All I find so far in searching are places that sell car radio SS vibrators 
(not to mention places selling the female toys ;-).

Thanks,  Chris

NNNN
