They were supposed to be non-inductive carbon, but need to find something better like carbon film.


Any resistor except a big wire wound is "non-inductive" on a low frequency like 160.

What you want is a composition type resistor, either metal or carbon, to handle surges without changing value.

The last thing you want is a film resistor, which is what you probably have right now. Carbon films or metal films increase in value after short duration high energy surges, because the surge blows part of the film layer away.
