I have an NAD 7175 Stereo Receiver which is working, but not producing any sound.
On the main power board, R709 & R711 are getting way too hot.
There is are burn marks on the circuit board, see attached pick.
I have replaced a diode and a couple of other components but have not figured out why there is heavy current draw. I have checked neighboring components and they seem ok. Am a bit new to circuit diagnosis, not sure where to look next.
Here is a link to the service manual.
