I'm repairing an almost new car amplifier, which I'm planning to use in my own car. The amp, is a Polk Audio PA660.
It was entering in protection mode.
I have found a pair of final transistors shorted at one of the channels(4 channel amp). I haven't found any other component blown or shorted.
Voltage, has dropped from 12V to 8.4V after a couple of seconds after start up.
It is possible that the only bad components are these two final transistors?
They are 2SD718/2SB688, it seems like they can be replaced with NTE36/37 transistors.
I have seen some videos on Youtube where people are replacing these two transistors and the amp it's good to go.
How come in a home theater receiver I have to replace a bunch of components?
I have also purchased, a mono version of the same series amp, which seems like it is in protection mode too. I will get it in the next couple of days.
Need amps in my new car.
