You should have some air between the resistors and the white wire. As you point out those 3K resistors get pretty warm. Take a moment to redress the white wire away from the resistors so it does not touch. You will notice that those resistors are at a slight angle where they go from the lower holes (7L, 9L) on one end to the upper hole (twisted end 3U). Work the wire so it goes under the twisted end (3U) as best you can.
NOTE: if you plan on installing the Speedball those 3K resistors are removed.
