Two versions GXR-82/D.

I have two versions of GXR-82/D. One has a large resistor and the other has same one with a tap on it at 20 ohms. Both have different pwr transformers with different wiring colors. The one with two large resistor, a 20 ohm and separate 450 ohm. This is the one I need wiring for. The 82 with the single resistor works fine. I have teardown pictures of everything ecept the different power supply types. Anyone have one to look at?
