Be aware that tantalum capacitors have a polarity. The type on one of my pac boards in C1 isn't a tantalum, so you can use a ceramic in it's place. I am pretty sure its used a decoupling capacitor
Visit http://www.rotheblog.com/ and scroll down the page. On the lower right you'll see the pac "lawnmower man" link. Best set of repair data collected in one place. Might help. Still want those caps?
