Back in the day (70s) W.W. Grainger sold these Lungren mouse trap buzzers in 6 or 12 VDC!   Measured over 1,000 violts from these guys from frame ground side.  Knock the crap out of you if you were earth grounded and held the buzzer while ir was powered up with 6VDC input!

Norm,
 
 I found an old buzzer from the 70's in a box of junk.  What did you used
 to do with these to study neutral spikes?
 
 Were you ever able to get one to ring continuously with the right
 capacitor and no other input besides momentary one?
