Thanks for your help. Morzh, I flipped the tube based on your assumption, and with the tube out, the notch was clear. Once reinserted, the pins made sense...however, pin 3 which was doing all the tailgating is very loose because that section of the tube base was cooked as well. I still get great continuity on the filaments, but nothing on the plate pins. I will desolder and disassemble as Terry suggested to see how cooked the wires are and finally see if my transformer has been toasted. BTW, the "Tar" is discoloration from the arching of the pins just in the area of that Rectifier. Thanks again for all of your input.
