If my question seems stupid it is because I am new to this and trying my
best to learn how to make repairs to some basic boards. OK Here goes:

I had to replace two barrel type capacitors on a control board for a pinball
machine. The capacitors were marked 470mfd35v and I replaced them with
nichion 470uf35v. I read that you had to reform capacitors when replacing
them. It that true for brand new capacitors or just used ones. Please email


Thanks for your help
