Default xtant 121m turn-on circuit help please...

i have an xtant121m that i'm working on. the remote turn-on circuit is cooked, basically. so far d23, r108, and q-31 are cooked, but i don't have the definite part numbers for them, nor a schematic to see what else could be damaged. i figure i might as well replace the 3525an for good measure, and since it appears to be an off-brand copy of the motorolla i have in the other working one, as well. i can use the working one for probing/comparison. any help would be great, thanks.
