[CQ-Contest] Repairing Dunestar 600 Filter

Has anyone had experience repairing Dunestar 600 filters?  I have a couple of them and occassionally a band will go out during or after a contest.
I have sent them back for repair and that works fine but it gets a little costly and inconvenient.

I suspect the problem is blown caps on particular bands but I can't seem to find the specs for replacement capacitors.

Specifically, I am wondering if anyone knows the values of the capacitors used in the Dunestar 600 (value, type, and voltage rating) and where I might find them.

I vaguely recall that there was an upgrade to these caps recommended somewhere.

Please respond either on or off the list.
