Thanks Ralph, that is what I was thinking but when they are advertised as
non-inductive you would think "non-inductive" wouldn't you. I guess I'll
have to dig around in some old junk boxes or parallel several 1 watters to
get them to work.
I appreciate your information.

I need to build a 3db pad, 50 ohm, 10 watt, to reduce the drive to my 6
meter amp. I need 2 X 300 ohms and 1 X 18 Ohm resistors and thought it

would
be an easy matter to find them with enough current rating to do the job

but
can't find anything larger than 1 watt carbon (not film, which are

somewhat
inductive ) resistors. I can find want is called non-inductive wire wound
resistors. I can't understand how a wire wound resistor can be
non-inductive. Could someone explain this?

By winding the wire so the inductance cancels out you get a noninductive
resistor. They are really noninductive at low frequencies. Once you get
above the audio range they become inductive. I doubt they would work for
your case.
