Working on a small working display of older working phones at home. So far I've got lots of Western sets, some 1A2, and a working MET set from a Dimension. Recently got some TIE EK-820 sets for the display that need a KSU.

Anyone know the whereabouts of a TIE EK-820, EK-1236, or EK-2260 KSU?

No, not totally crazy. Just a little bit. Have lots of spare fuses on hand!
