Question about NAD 2200 2Channel Amplifier
Have you checked the continuity of the primary windings of your amp's tranformer?. You have already stated that your amp went dead. If it is so, there must be some fault inside it, a fuse is blown, a shorted rectifier, a shorted filter capacitor, shorted output transitors or so. If so the mains fuse will blow out. have it happened in your amp?
Anyway the colour code cannot be predicted as Nad has different colour codes used for their primary winding input to their transformers. You just do one thing. The transformer primary have tappings in it, to input various voltage inputs, and that tapping are comming out in different colored wires. Measure the resistance of the winings, with a multimeter set to ohms range. One end of the winding will be direct, and the other end is tapped for different voltage inputs. The maximum resistance winding which you gets with respect to the common direct end will be meant for 240V, and next lesser meant for 220V. Leave the other ends free, and insulate its ends without touching each other, or touching in on the chasis. OK.
