i have an sts ksu that clicks and it gets worse if i put in a card. the voltage is 10 vac but if i take out the fuse it jumps to 30 vac. does this sound like the transformer is shot. default doesnt help. thanks. dave

The KSU needs replacing, the power supply is shot. I called it the click of death back when I was still doing what you do.

yeah i think it is the click of death
