|This applies most particularly to Mike Ross, but anyone else who tries to put a KL-10 into running order needs to be aware of this.|
The muffin-style fans used for cooling on the main power supply have at best a 10 year working life, less if they have sleeve bearings rather than ball bearings. We had an outage on the 2065 this week when a dead fan caused a heat-related failure in one of the large power bricks. The brick can probably be repaired--power transistors are still common in the world--but even so.
We also lost an H744 5V regulator in the 11's power train during a lightning storm a couple of weeks ago. One of the large input power traces under the small filter caps (roughly 5mm across) had a 5mm circle melted out of it, with scorching of the cap.
So condition your power as much as you can, and watch those fans!
