Hi, Does anyone have a 12-469 that they could tell me what the part number markings are on the headphone amp chip? Its the 8 pin device thats between the volume control and the ferrite rod antenna, designated as U1 on the pcb. My 469 has the markings rubbed off the top of the chip, and I need to know what they are. Any help greatly appreciated. JEFF
