Recently I have obtained and have been maintain several pinball machines. On one of them, the 6v winding on the transformer is producing 7.3V. I am also having dificlty keeping lamps in this machine, they burn out faster (a week or so) then I think they should. My idea is that the 20% over voltage is the root cause. I have inspected the transformer hoping the someone had moved a connection to increase the brightness of the bulbs. I would like to turn down the intensity a bit. My first concept is to put a 2500mF (if I did the arithmetic right that should drop about 1V at 60hz. My uncertainty is how much current a cap will carry? I am not going to blow it up am I? There are many bulbs being fed by this so may be carring more then 1A . Basic question is what is the current carrying capacity of a capacitor?
