SOURCE: nad 304 amplifier no output, relais not willing to
The 2 BIAS resistors of 47kohm, R333 R334, replaced with new 1W resistors. 1 resistor was totally open and 1 resistor was 55k.
It were 1/2W resistors, replaced them with 1W resistors. Very low cost repair for a High End amplifier. Should live for another 10 years.

Marc

Try unplugging all of the speakers and see if that amp is still distressed. If it looks clean and happy start adding speakers until it returns (or not).

These depends on the model of your CD player, use the corresponding
RCA plug or a 3.5mm plug for portable CD player to the Tape Input
of your NAD 3150
