For re-forming the cap'sin my unit, my plan is to (hopefully this weekend), disconnect the screw terminals and use a programmable power supply [DC] applied direcly to the terminals. Current will be limited and the voltage slowly increased. If I can get the lab computer working, then it will be a nice slow smooth increase over a 12-24hr period. If I resort to adjusting the supplies manually I will end up making larger steps and watching the current..not as clean but still better than a full "bang".
