First pic is the offending part, can't probably see the scorch marks very well, or smell it either. Second picture is the transmitter, whoever built it did a fairly good job, except for the front panel. Notice that it is clamped to the top of the rack rather than being installed in the rack, well that's because the builder used masonite for the panel but it is slightly under 19 inches and the holes are drilled too far inward to fit on the rack but are too far outward on the panel to drill out to fit without destroying the panel. Eventually i want to replace it with a metal panel and paint it to match the rest of my gear in that rack. Third pic is the rest of the rack, the 811 modulator is bottom, then the power supply for the 807 transmitter and the Millen exciter, and the Millen 90800 exciter is the piece above the power supply.
