After power-up, switched to “Speaker A” and there was a loud “pop” noise followed by a burning smell. The device was immediately disconnected from power. Because of this, we were unable to verify the functionality of inputs or outputs before power was removed. Additional observations before unplugging. Most tuner backlights, meter lamps, and input selector lights were working at the time of power-up. No further troubleshooting or repairs were attempted. Standard signs of use. May have cosmetic wear and/or scuffs. Yellow tarnished tint on faceplate, and some damage to metal finish. Chipped areas of veneer on side panels at the back edges. See photos for more detail. Includes only what is pictured. Does not include any additional components. R2v3 CATEGORY C4/F3 NON-DATA.
