Bringing up old power supplies slowly.



I have several cases with motherboards and power supplies that haven’t be used for several years.


I have been told the old capacitors need to have voltage applied slowly to avoid problems.


I have 0 to 120 VAC variable transformer


I have two question about how and when to use it:


1.  How long do I take to go through the whole voltage range?  12 hours, 3 days, a week?


2. How long can a power supply be unused until I should do this procedure again?


Thanks for any help you can give,

Nick is definitely correct on this. I've purchased this type as well and actually received them with the terminals pressed completely out of the socket housing. They work great for a quick one-off test, but the springiness of the legs on the chip contribute more to holding them in place than the socket itself. The Jameco sockets are generally good quality at a reasonable price.
