Did I ever say that?  No.  Someone questioned the fact that I stated that 
a resistor has a self resonant frequency.  I have never claimed that it 
mattered in an HF amplifier.  Also, I even stated in once post that the 
resonant frequency of the resistor is probably very high due to the small 
values of the parasitic L and C.

So I still stand by my point: A resistor has a self resonant frequency.  
That is all I was trying to say.

However, that 10 nH of inductance WILL have an effect on the anode 
circuit in an HF amp.  So while the self resonant frequency is not an 
issue for HF, the inductance still is.
