The two large black caps in the foreground are the surviving 105C
caps, while the blue caps in the background, are the bulging 85C caps.

** Errr - I hate to tell you this pal ........

but the pic shows all 4 caps installed with reverse polarity.

A smaller cap ( C310) is clearly installed correctly and so are all the
others I can see.

The markings on the PCB are a bit unusual with the white triangle
indicating
positive.

AAAAAAARGH! I can't believe I did that. I usually assume that the
silk screened marker was matches the negative stripe on the
electrolytics. Very embarrassing.

Thanks for catching my mistake (as I crawl back into my hole and
sulk).
