Relax,As far as what T_K mentioned on voltage rating, well, you are only dropping 45 VDC across the resistor, so its not a concern.
I would use the 50 Watt resistor bolted to your existing chassis, because you do NOT need to dissipate 50 Watts, only 8.1 Watts continuous.
Also, you can use the chassis to keep your Chipotle Burrito warm. Yumm.
Another alternative, use two 500 Ohm 13 Watt power resistors in parallel, to become 250 Ohms at 26 Watts rated. I sonically prefer Mills MRA-12s, twelve watters, but if in series to the Output tubes, I always prefer near zero or minimum resistances !!.
