Hi

I pulled the transformer from a dead bug zapper last night. It looks just like 
in your picture but with the potted in cap still in place. I broke out the 
high voltage probe and measured 3.56kV and 10mA. That does not look right 
compared to the snappy spark.  Spark will start at about 1/8 in gap and once 
started will not break until the gap is stretched to about 3/8 in. I figure 
the cap is messing with the measurements. 

I tried to measure the capacitance, the meter says 9nf but flashes back and 
forth between that and OL. I was wondering if you were able to determine the 
value of the cap in yours when you removed it, or if it was destroyed "value 
unknown".  It would be an interesting experiment to see what can be done with 
the original cap in its original position. At such a low power level it may 
well work O.K. lossy as it may be. 

Just curious,

deano
