Default Velodyne ct-80 project

I have gotten hold of a velodyne ct-80 that wasnīt working. I popped it open and found that the previous owner had removed the filter caps (which by the way probably were fried) and two power transistors. I would like to get hold of a schematic so i can replace these parts. FYI the rest of the transistors were tip 29-tip32 and some d882, a669, b649A and d669A. Another strange thing is that i couldnīt find the fuse.
Does anybody own one of these and could check what transistor q709, q710 are and c801 & c802

I got an answer from velodyne. The caps are regular 4700/63V, but the transistors missing are 2sa1386 and 2sc3519, which arenīt available here. Any suggestions for replacements? I am thinking of TIP35C and TIP36C (which i can get quite easily) or NJW0302 and NJW0281G.
