Default Onkyo A8700 Blowing fuse

I have this dead amp. I replaced all 8 transistors hoping it was the problem because one had a burnt leg. Thanks in advance for some tips on finding the problem without damaging the new transistors. The burnt leg was pin 3 of a C3855 NPN transistor.

Are the 2SC3855 the output transistors?

Yes they. In pair with A1491. I just found an open resistor at the location of the previously burned C3855.
