Smile Fried PPI, need part numbers.

Hi guys. First off, I am an amateur on amp repair. I know how to solder alright-ish, transistor testing, familiar with a DMM, and grasp the concept of what most components do. This amp isn't that great at all but its just a learning thing... I've got a PPI A1000/2. Voice coil bottomed out on a Type and the amp blew 6/8 of its power transistors clean and the other 2 were badly burnt, as well as 2 other "things." I already ordered 10 irf3205's, but there are 2 other components right under the input RCA whatevers that are clearly connected to the input RCA's on undersde of the board. Can anybody help me identify these 2 resistors(?)? They are toasted and I can't find any schematics to ID them. I went over the whole amp and couldn't find another "thing" that was the same size to even attempt get the part #. They were all way smaller so yeah.. I'm a little lost.

Many thanks, B.
