One side-effect is that you run into possibilities of oscillation. This have happend and was the cause of a GPS outage in a US Harbour a few years back. What was a wise design became an enemy due to a subtle change in part. Don't recall if the part was replaced by an "equivalent" or same part-number, but the new version didn't work as expected during all conditions...


Yes, one of the most probable problems. I've read the story about the GPS outage in that harbour, as I remember it was caused by a failure in one TV antenna amplifier on a boat - but I don't remember if it was an isolated case due to a failure (or to a bad repair replacing the part with a similar one), or was a more 'endemic' problem :)
