I have a Heathkit Warrior, so are you saying it is safe to remove the
neutralization cap? And if so what kind of provision should be made in its
place? I have a Warrior that burns up parasitic suppressers and makes loud
crackling sound when HV is turned on and biased by a terminal being grounded
during tx/rec. I replace the parasitic suppressers, checked the
neutralizing gap, and replaced tubes and it still does it. Needless to say
its been sitting on the bench for a few months because of frustration.
