I have a 25w resistor that is adjustable. It is a wirewound ceramic tube. The windings are exposed along a narrow strip. It has a sliding contact that lets one adjust for any ohm value desired. This is great for dialing in the value you like. Ideal for your situation.

I don't know if such is still manufactured anymore but surely they can be found on eBay, etc.
