Parasitic Suppressor

I am in the process of building a VT-4-C (211) Hartley Oscillator
transmitter and have only a few 2 watt composition resistors with
which to build a parasitic suppressor for the plate.  They are:

   1 ea.  10 ohm 2 watt composition
   2 ea.  15 ohm 2 watt composition
   1 ea. 100 ohm 2 watt composition
   1 ea. 150 ohm 2 watt composition

Since I don't have the foggiest idea where I can get any others,
I am asking those of you that are knowledgeable about such things,
which of these might make the best resistor around which to wind
a coil for parasitic suppression on an 80 meter Hartley?

Also, would like to insert, close to the grid pin on the socket,
another resistor to act as a parasitic suppressor.  Which of those
I have available would accomplish this?

My purpose is to make a vintage 211 Hartley Oscillator transmitter
on an oak bread board and make it as close to the original open
breadboard design as I can and yet still have something that won't
tear up everyone's TV set.

Any help will be appreciated.
