How can you agree, Rich, when even you admit there is no such thing as a
"non-inductive" resistor?

Yes, you are correct here. I think what I hear you saying is that the
inductance of the resistor is small enough that it really doesn't have
that much effect on the overal resonance of the anode circuit. It causes
a slight shift, but not a huge one as Peter had suggested. Do I read you
correct?
