NAD T765 receiver in protect mode. Don't have the schematic. There were 3 bad devices, but at the time i only found 2, so when i replaced the two outputs, it went up in smoke. Then after a little more digging, found an SMD device (think transistor) that is feeding the outputs is also shorted. It looks like a G1 with a sideways U. Maybe a MMBT5551 (2N5551 leaded equiv). Any advice would be a great help. Attached a closeup photo.
thx paul |
