Have you tried Play Things of the Past for your resistor?
RS Electronics has a 25 watt power resistor that adjusts from 1 ohm to 25K ohms. You adjust the slider on the resistor and when you have it at the value you want, you tighten the slider so that is is in effec a "fixed" resistance.

That's no good anyhow, they have a minimum quantity on most of their parts. Try Mouser they seem to have ones that are close:

P.S Why do they have a shunt from B+ to ground? Something like that between B- and the chassis makes sense? Is this related to the shadow meter?
