Used every day,on FM, until one day, switching on and very low level audio out. Tuning is fine on FM and AM is normal. Phono and Aux inputs to amplifier are normal. Schematic on elektrotanya. Nothing loose found on twizzling. There are some ceramic resonator filters, I'm aware of silver migration over such time spans , resulting in attenuation of throughput, anything else to zero-in on? Lots of Din connectors connecting tuner to preamp and amp, power , signal and control connections. Any advice on improving contacts other than needle insertion to tension up the socket yokes a bit.
