The best part of it is that you did not use any inert gas? I have a handful of 4700 uF caps - some fast, some not - in a drawer here, might just do the job... I'll experiment around next few days. Please share any details you might remember - voltage, capacitance etc., I mean ballpark range. Dimiter
