This problem can be partly solved by " grid leak " or any kind of automatic gain control, but the downside of this is surrendering control over receiver to noises and fadings of input signal, which is undesirable.

When the grid leak stage had a transformer input, the valve grid connected to one end of the transformer secondary, and the other end of the secondary went to ground via the grid leak resistor and a small bypass capacitor.
