1) the big capacitor in the middle of the victor was marked with a big red X sign .
2) on the board inside the victor there was written :" victor 883 rev F" and not victor 884.



does the big X mean it was already bad ? why did the board inside the victor siad victor 883 and not 884? why did the victor overloaded and not the 40amps circuit breaker?

If you happend to be drilling/cutting/removing material from your chassis near the Victors, there's a chance some shavings may have fallen in. That is how I've seen a few Victors release the magic smoke.

It's not a bad idea to blow out your Victors with compressed air before you fire them up.

BTW, most of the time, the X's marked on capacitors are put on by QA people to indicate it was installed in the right direction. So generally, it's a good sign =).
