Hi guys, I have a fault in a mixer tascam, it has volume, but with distortion, although the gain is not even in the middle, apart one of the channels (R) sounds very low, already change some damaged resistors and also condensers, clean the potentiometers but nothing, there are several operational amplifiers but I do not know which of them is the one that is giving me the fault, its code is njm4565ld. First of all, Thanks.

THAT PROBLEM YOU WILL HAVE IT IN THE INTEGRATES OF THE LINEARS OF PRE ... IF THE CHANGES ALL OF ONE DO NOT BATTLES. CECA IF SOME WILL BE HOT ... BIRDS ARE NOT SAFE WHAT IF YOU DO NOT HAVE TOOLS TO TRACK THE SIGNAL. REGULAR THOSE THAT ARE DAMAGED ARE THE OF THE DEPARTURE. IN THE HEADPHONES DO YOU HEAR THE SAME?

Thanks for your reply JLMRNEO, the sound if it is clear when using headphones, the problem is that I can not find the diagram to see which is the amp. of output.

Colleague commented that I found the manual of the mixer, there were 2 amp in short, obviously I changed them, and now this is great, when I changed it I noticed that when the volume increased, I heard choppy and also change the potentiometer fader of the master, thanks for your suggestion.
Greetings.
