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. Edited by coper - 25 June 2022 at 12:28pm |
