It won't be much different than this one.

I replace the burnt parts in both ch.now i am getting -27.6 volts on pin 4 of all opamps.Q13 -regulator is getting hot and Q14 is also getting hot.I replace Q13 with a used one but no change.any ideas what can cause that?
Q13
1:23.7v
2:33.5v
3:29.6v
Q114
1:31.5v
2:36.4v
331.9v

Pull the regulators and verify the voltage on the op-amps goes away. I would then lift the supply pins on the op-amps and re-install the regulators. Check the voltage on the outputs +-15. If those seem ok, replace the op-amps. I don't believe those parts can take that much supply voltage.
when i remove the regulators the amp thermal light comes on.
Q13 and Q114 used to get hot.
The amp has no rail voltage now.If i pull the center leg of the rectifires i get rail voltage on the center legs.All outputs are out of the amp right now.I dont no what to check now.Any idea?

I install all outputs and i leave Q114 out of the circuit,with R124 in circuit i get -31v on pin 4 of all opamps so i removed it and now i have - +12.6v on pin 4 and 8.I check for audio.The right ch has good audio and the left is distorted.This amp is giving me a serious beating.
