re: NAD 2400

Blew it with high volume STING&The POLICE... How can I trouble shoot?
Can it be as simple as a fuse?
If so where would/they be?
Any Help appreciated

re: NAD 2400

There are 4 fuses located on the Main / Supply P.C.B. (J028A) inside the Amp.

I would recommend replacing all the fuses as they tend to weaken over time.

Should any fuses blow again, note the location and return here for more help. Be advised that the power supply uses fusible resistors.
