Hi,

I'm trying to repair a QSC PLD4.2 amplifier and I don't know what the original SMPS transistors are.
The transistors are Q64 and Q65. This amplifier has already been repaired and someone put in a STP11NM60FD and a STP45N65M5! One of them is shorted.
Does anyone know what the original references are ?

Thanks.
