Can anyone out there identify these power capacitors?
If it wasn't clear enough - the capacitor colours are metallic red and grey-white.
Markings on the capacitor are as follows -
on one side:
'Elna' (brand obviously)
'(M)' (??)
'16V/2200uF' (rating obviously)
and on the other side:
'CE105C' (temp rating I believe)
'9722' or '9714' (batch numbers perhaps?)
'S' (S is within a circle)
Anyone?
An externally hosted image should be here but it was not working when we last tested it.

M appears to signify A tolerance of +-20%
Not sure about the 'S' though.
The Elna website is quite thorough but I'm sure that you have already looked there.
A useful guide to cap markings is at the bottom of this page:

Is this Elna's standard range? I've only ever used cerafines or Silmics myself but I like the pretty colours on these.

I have since replaced them with Panasonic FCs and FMs - now at least I know that that was not a bad decision.
Damon, my experience with electrolytics in general has led me to err on the side of caution. In contrast to you, I've seen caps in old tube testers go dry in just 30 years too!
