Please help me anyone.......
My amp suddenly shut up(no loud playing), the led in front is red instead
of
green.I`ve measured the output and that`s ok. I can`t find out what`s
wrong.
To solve this, I need a schematic or a very good tip. Hope someone out
there
can help me with this

Thanks.....




From Google :

Usually this means a blown channel - bad output transistors and possibly
other
parts as well. My 304 had a bad 3.3 K resistor which caused this, however.
I
am a repair tech by trade, though - can't really recommend trying to fix it
yourself if you're a newbie or DIY'er. Too many ways of messing it up worse,
and NAD's are somewhat "special" to repair. Parts such as transistors which
can be readily "subbed" in many other units often don't _quite_ work in
the
NAD, requiring special ordering from NAD.



Another service note I forgot about is to check R333(left) and R334
(right channel). These are 47K ohm, half watt resistors. If they open
the channel will have 10-15V of DC offset and the muting relay will not
turn on.
