Question about NAD T763 Receiver
NAD T763 Amplifiers will not turn on. Unit has been used for 4 years with no problems. I notice that even without a load connected the speaker relays do not switch on.
Some of these units have a circuit protection system that is made with capacitors and/or resistors. The caps can become overheated and eventually wear out. The relays themselves can also become faulty which seems most likely in your case. How is the fuse? Have you check the power form the main power supply to the circuit board? THere should be a label on the inside somewhere that says the DC voltage output. The mulit-meter you use to test it should match the sticker voltage output rating.
