Age (even if they are just sitting on the inventory shelf)
Overheating (due to a faulty cabinet or panel cooling fans)
Dirty environment
Faulty repairs (mostly caused by poor quality replacement parts)
Poor installation (Damage that might not be evident right away)
Before MK V power supplies fail, they get “noisy.” That means one or more of the output voltages becomes erratic or is “piggybacked” with an AC voltage.Visually, it might look like this picture. See the cracked resistors? This could be caused by heat or age and probably contributes to MK V power supply failure.Powergenics has engineered a refurbishment solution that completely eliminates this “noise”. We replace high failure rate components with higher quality, tighter-tolerance parts resulting in cleaner output voltages for a longer period of time. Since these components are more robust, they will resist heat and age degradation, resulting in a longer life power supply. Here is the same chart showing the output voltage after the Powergenics refurbishment:(Notice the scale is 500mv/division instead of 1V/division!)
