I have worked out all the math, and have set on components and values. What I am not sure about are how to orient the resistors in the oil. I am thinking if I mount the plates vertical, with the resistors horizonal, then i will get better cooling. Also, where in the oil should they be? My thinking is if I mount them in the lower part of the can, then the convection currents should pull the cooler oil down to the resistors. Also, use strips of copper to connect the resistor bank to the SO-239 instead of wire. Anything I havent thought of? TNX for your help.
