Hello.
The right channel of my NAD C326BEE is dead.
Main amplifier works fine on two channels.
Pre amp with headphones or speakers no right channel.
No music,but very great cracks.
I m not ingeneer,but I like electronics.
I have a multimeter,and I ordered audio signal tracer.
Help me please for repair.
It s the file of right channel cracking.
Regards

Can you post a schematic of the thing?. How old are capacitors? Had you replaced them, total or partially any of them? Do you know how the fault start (after a short, a travel, a voltage spike in the input, a transient, a drop to the floor, et cetera)?
Thank you.
No,don't replaced caps, amplifier is 6 years old.
Any idea for problem,it's amplifier of my dother.
She said one day zero music in the right channel......

Sounds like a failing component/dry connection, cold-spray or a poking stick (non conducting!) might be the best way to localize the fault.
Hello.
I recived my audio tracer.
The signal stop and cracks on C320.
I verified out module,signal stop on collector of Q359.On base and emitter signal is ok
I replaced Q359 it's ok,good signal on collector,good signal not cracked on C320 but 2 min later the same situation
Nothing on C320, nothing after collector of Q359.....
18v ok.
I desoldered the q359 on little China DAC 5V it's was marked G1....i think it's it the same MMBT5550LT1G.
