All resistors are inductive, Mr. Rauch. All conductors are inductive.
The question is how much inductance? According to Wes, the Matsushita
resistors we use in our VHF parasite suppressors have about 0.01uH of
intrinsic inductance.

It will probably be a while before a transistor HF amplifier will be
built which equals the power ability and the 62% efficiency of the --
close your eyes so you don't puke, Carl -- X-2159 (22.5kV/125A=90 ohms
RL).
IMO, current transistor technology is becoming obsolete Just as
germanium- crystal semiconductors were superceeded by silicon-crystal
semiconductors, the latter will be superceeded by carbon-crystal
semiconductors.
