D35 is a 36V bidirectional TVS. Model SMBJ36CA.

D67 is an 1A, 60V shottky diode. Any diode with these charactristics or better will work.

Dear sir
I had tried to replace the Diode D10 from AX3500. It is connected with R18 & R9. But unfortunately while de-soldering resistance R9 along with track comes out.Now connectivity between R9 with D9 and D10 is OK but connectivity between R9 and small PTH is creating a problem for me. Where this PHT connected? How I can check it? I have found the same PHT on other pair such R1-D12 and so on. Can you explain me what is the interfacing arrangement? So that i can easily debug it.
