This could also be a bad coupling capacitor between the AF pre-amp tube (EBC41 or EAF42) and the power output tube (EL41). The grid bias voltage of the EL41 will become too high, resulting in a poor AF quality. Check out all the capacitors in the AF stage, and replace all which have developed a parallel resistance below 500 k.
