Hello
I repaired power supply a of amplifier KIPUS MZ-70, (amplifier very similar to SPL DYNAMICS D7s), suffered a reverse polarity and exploited all transistors (IRFP064N) and gate transistors and IC TL494.
Is completely repaired the amplifier and transmit audio without distortion, but I have noticed that the output transistors (IRPF360LC), slightly increases its temperature without charge ... The transistor gate has a square wave and the voltage rail is + 122v and -126v ...
Why this increase in temperature of the IRFP360LC?
Greetings.
