I highly doubt any of them are loose but I imagine I could have done a better job!

It may be possible I bridged under a cap slightly... hmm.

Also the largest cap on the board was difficult to replace as the solder point on the end closer to the middle of the board was quite hard to get the cap wire through. If I ever do this again I'll probably go with regular caps or at least non tantalum caps with leads rather than SMD caps.
