Greetings, I'm new here!


I'm tinkering with a discarded Symmetricom Timesource 2700 which won't lock. After letting it cook for a few days, the Rb alarms never went away, so I opened it up and connected directly to the serial pins of the PRS10 inside. This allowed me to run Stanford RbMon, which showed the high lamp drain, high fet voltage, and other symptoms of the lamp not starting. I did some digging and found that I'm not the first to experience this:

So, I opened the unit up and went whisker-hunting. Didn't find any, but inside the lamp enclosure, I found this:

I'm fairly certain the cracked fellow on the left is the problem! Trouble is, there's either no silkscreen on this little board, or it's too charred to read. I'm pretty sure that's C900 (2.2uF 35V radial Tantalum), but I'd like to be sure before dropping one in there. 


The PRS10 manual has a full parts list and makes numerous references to the schematic, but the schematic itself isn't part of the document. Anyone able to confirm the identity of the part I'm looking at here?


(Also, how the heck do I get it out of there? And should I attempt to clean the residue from the rest of the enclosure?)


Thanks a bunch,
