Tom,

How can a series resistance of 100 Ohms or so be greater than the K-Ohm 
impedance of the anode circuit?

The conventional concept of a supressor is that the coil chokes the VHF 
signal and the resistor then absorbs it.  However, if you think about 
impedances and such, that doesn't make sense.
