Attached is a schematic for a power supply. On the far right had side is a ground symbol which appears to be connected to the 2N3055 emitters (through the 82 ohm resistors), but that line is supposed to have the output to P3. M1 and I1 and M2 and I2 are the outputs to the analog to digital converter readouts. The 2n3055 transistors fried and the 82 ohm ceramic wire wound resistors fried, and I have replaced these components, but I am not getting any output voltage at x2 and x4. Can someone explain the ground symbol on the far right side? Thank you.
