This is a comparison between my new acquisition, a 9,000 volt 150 mA NST (top left) and a heavy duty truck battery (lower right).  The NST actually out-weighs the battery by a considerable amount.  The NST is rated at 9,000 volts, 150mA.  I'm hoping that once all of the tar comes off, I can punch out some of the shunts and get 450 mA with some type of respectable life time.

More on this project later!
