Hi Craig,
You would think that should be the case but as I commented on a recent thread, I've got a whole bunch of Tek 7000 series stuff working over the last couple of years, most recently the 7912AD and I guess I've replaced well over a dozen dead-short Tants in that time.
All bar one was blue, the other was 'brown with stripes' none have been yellow or orange. Yet, I would say that an (unscientifically derived) statistic is there are more yellow & orange Tants present in the equipment. Now, I've not looked to see if, for instance yellow/orange are always 5V and so on - just my observation - along with the comment I have worked on as much HP gear and have never had to replace a single Tant in that but don't even know if they used them though!
I assume the colour may be an indicator of manufacturer (the yellow is very 'AVX'?) I wonder if anyone else has noticed a colour bias in the failure rate?
...I now await a puff of (yellow/orange) smoke from the bench......
Adrian
