R25 was a 150 R2 & r3 were also out of tolerance if replacing those wouldnt make a difference not sure what the problem is.

the 5w resistors read .7 ohms

i replaced the driver transistors with nte 128

and output transistors with MJ15001G one blew again so i replaced with nte 181npn

i think when i replaced the driver transistors the one legs got shorted to the heat sink box
