John, I was able to get 3 repaired so far. I have about 8 I haven't looked at yet. I've had some failures on some as well. It is a great learning experience.

That's good, what is your average time to repair one of the boards?

I just make sure to run them at under 16 volts (to not over tax them). Is there anything else you guys would do or should i just have my dealer upgrade them now before the inevitable failure? Or is that true - is it inevitable that these will fail before the ps2 3 volt boards?

Nothing is inevitable, the 5V boards may outlive you.  While it's true that they are more prone to failure than 3V boards, there's no certainty that a specific 5V board will fail, some may last another 20 years.  I just run them until something goes wrong.  I do inspect them and replace any suspect caps that I can reach.
