Both AM and FM have only hiss when normally played , but some signal is found with a tracer at some points on both bands? Something common to both. I'm not looking at a schematic but would need one to fix it, do you have a schematic/service manual? HiFi Engine.com might have one. I'd check low voltages on power supply to later tuner stages, something common to both.
