This particular power supply is a model year 2006 SPS600-2-0020, but I think most SPS rack supplies in the range will have similar circuitry. I fixed the power supply, but I have a buldging capacitor that needs to be addressed. Problem is, it looks like someone has already been shit-rigging the area in question, it's a mish-mosh of caps, brands and values and I am not sure any are correct. The one marked in red is the one that is bulging, but I could use the value of the ones marked in blue as well if possible, please. 

I have scoured the web for a schematic, parts list or service manual, no luck. Amrel power supplies division was sold to Ametek in 2010 I think. I sent an email to Ametek and they were far from helpful, in fact quite "dick-ish"
Any help much appreciated C117 & C120-126 are the ones I really need the value for.

Thank You!

No one? Maybe a guru can tell me what I'm looking at here? Is this a filter section? Any idea the ramifications of the wrong capacitance in this section? If I just pop in some 1000uf caps?

Thank You.

Reasonably low power SMPS, so pretty much any value from 470uF to 1000uF of the appropriate voltage 105C low ESR capacitor will do there. However I would change all of them as well, unless they are the original Matsushita ( Panasonic) ones. Just make sure the ripple current rating is high enough, from the rectifier diodes anything over 1500mA would do.

 I plan to do them all, I don't see any Panasonic's, but that's likely what I will put in. The price was right at $45 and the repair was inexpensive as well. Don't know how often I  will need it, but its nice to have a higher voltage unit in the rack at that cost. Thank you, I appreciate the information.
