Hi Everyone,
I am trying to fix a NAD C320 stereo integrated amp. The left channel has no sound. When I "ON" the amplifier, I hear a "click" sound on the left channel and nothing after that, but the right channel is perfect. When I plug the inputs directly into the "Main In", both channels are perfect. When I plug the Right channel "Pre Out" directly into a power amp, it is OK. When plugging the Left channel "Pre Out", there is no sound. This confirmed that the problem is in the Preamp circuit. I have checked all the transistor, diodes and resistors in the Preamp and they are all OK. It would be of great help if someone can provide me a schematic of this amp or provide me a clue what can be wrong. Can it be the Volume Pot?
Thank you
