the amp was in protect mode(red led),i found 3 transistor shorted two for power suply 70n06 and one from audio irf640n,i change them now the green led is one but i dont have power for the suply
if you can tel me what tension i have to measure
the protection relay is ok
i measured the tension to the curent to the power that suply the amplifire,i put the voltmeter from +to - and when conect the remot the tension break from 12v to 8v and the curent is 3.9 amp
Did you check all of the gate resistors and the power supply driver transistors?
I'm assuming that you have replaced or removed all defective transistors. If that's not correct, please precisely describe the current condition of the amplifier.
