View attachment 1078008 View attachment 1078008 I have a non operational NAD 3060 - it has one VU meter illuminated upon switching on relay indicated on image clicking on approx 30 secs after powering up fuse indicated on image tests OK for continuity inspected all caps for signs of leakage, swelling etc nothing obvious no obvious burned components faint hum from transformer I would say is normal ? I tried both main and remote speaker outlets, and aux / phono inputs using an Ipod as a sound source. I have looked on HiFi Engine for a schematic and searched elsewhere to no avail. I assume that the power supply is at least partially functional seeing as the VU light is working at lower than mains voltage (240v nominal) I have a basic understanding of electronics but would really appreciate some suggestions on how to diagnose this problem please. It's hard when you only have a basic idea of the way the sub assemblies of the amp fit together. Any help or suggestions greatly appreciated and how do you guys approach repair without a schematic or at least some kind of block diagram? Yeah I know experience well hopefully that is what I may gain here after some time. Thanks for your time in reading this, Peter.
