Hi Dariusz,
I have the NAD C370, For some strange reason it blew the the fuse by the on/off switch, I replaced it & it worked ok for a few days, then blew again. I disconnected the leads to the main board, put another fuse in, blew again, disconnected the supply to transformer, put fuse in, didn't blow, reconnected supply, didn't blow, reconnected to main board, didn't blow & powered up, switched it on & off a few times, then blew again. Is it possible the transformer has a intermitent fault? Please can you help, I'm really stuck on this.

You have a short somewhere in the system. Maybe one of the lock actuators or a switch. To test disconnect all locks and switch then replace fuse if don't blow start with driver door and reconnect lock check fuse see if it blew if not reconnect switch active lock check fuse see if ok. Continue with each door separate using same steps until fuse no good you will have found short. Replace shorted part.
Hi, check the remainder of the fuse's chances are you have blown more than one fuse, if they are all ok then you may have blown one of the main fuse's which are located in a fuse box in the engine compartment.
Hello
All telivisions are provided with fuses, and the function of fuse is to protect its internal circuit agains short circuit, and protect the other components in the TV. if fuse must blow, surely there must ba reason. Without rectify that reason, if you put the fuse and switch it again, it may poise to other more problems. So get it repaired with a qulaified service personal. Never put any more fuse in it and swich on the Tv. Ok.
The AH may denote "slo-blo" style as opposed to Fast-acting A fast-acting fuse will look like a single strand of wire ( maybe wiggly looking) ..A Slo-blo will have an element in it and a spring

Read page nine for some simple troubleshooting tips and see if that helps.
It *could* be a fuse but given you've owned it for a while and NAD amps often have capacitor issues in the power supply, chances are it needs some serious work by a good tech. Contact NAD directly and see what they recommend.
the start and run capacitors of the compressor can go short circuit and cause a big spike that can blow the bulbs, trip fuse etc. Inspect the capacitors for splits etc, you may well find that the start cap has blown and so there will not be enough current to get the compressor running.
With closed eyes -replace all capacitors on protection PCB
All of those caps are overheated and dry out (they lost there capacidance).Note that capacidance meter will not help you at all.
Now unit will work.
BUT!!!
Most important!!!
Check four big filter capacitors in the middle of unit!!!!
If they are white (NAD 10000uF/80V) DO NOT USE UNIT AT ALL!!!!
FIRE HAZARD!!!!!

I had the same problem with mine AV713 it turns out to be the relais of the power unit (left site above the transformer).
solution may be to replace it with http://ecb.omron.com.sg/pdf/relay/power/G5PA-1.pdf e.g.
good luck TB
Hi there,
I would think that you have blown your bass drivers in the speakers. Sometime you may have a fuse which is blown in the speaker but this is not usual. Try on another speaker if you can.
