I am trying to repair a channel on this amp and found some shorts on the driver card and when I removed it the two suspects fell off the card. Should I try to replace them? What is the small one? Or should I try to build a new one? I found a company that sells replacement cards but they look different, how would I check what components go on the new card?

The person selling the board would have to give you a list of the parts.
The pads on your board appear to be gone.
The smaller transistor will have markings that you can use to look up the original part number.

So I was able to get the people selling the card to provide me with a schematic for the card. can anybody make this?? I want to try but am having trouble understanding the schematic and have not tried something like it before. I know a lot of people search for replacements and never seem to find any..

I wonder if someone would make a hybrid type board with a mounted aluminum sink to be able to clamp equivalent transistors to, for the ones that get the hottest and destroy the pads? Are the transistors failing, or just getting so hot they overload the thermal capacity of the boards? I have two A600.2 amps and those two boards are the only things that concern me.
I have found a source for fully assembled universal replacement for the ceramic PPI driver cards!! if you need them you can contact me.
I’m guessing these aren’t available any more? I’m needing 2 sets to get a A600 and A600.2 operational again.
