Ah, it is now because I have inserted resistance to the grid, before there was none at all.
So perhaps my innovative fix is not so heinous at all.
Set "B" is being difficult as well. As it had been twiddled I set about realigning it first.
The IF transformers will peak on one coil but not the other and there is a heterodyne whistle at one place on the tuning cap.
The MW oscillator coil will not tune to 600kc/s as it should either.
Seems the coils have suffered damp or there are mica caps that have drifted.
Got poor reception on MW and LW but it needs work, its also not loud.
Checked all the valves by substitution, HT is well up to the mark.
