yes that's what works for most people, but a little higher or lower
should be fine (its just an efficiency thing, but electroporation is
way more efficient than CaCl2), I think the sparkers put out ~18kV

You've tried once or twice already without it working... the
instructions I just gave are
pretty simple, I think its worth a try! (Just make sure your amp
concentration is right this time!)
