I have drawn red circles where normally you should isolate the regulator sections, does your (15 and 15s) and -15 and -15s) pins are connected together ?? The S lines are normally senses line ...
The green voltages values on the x-former secondary side are definitely wrong
Have you tested the main capacitors for shorts leakage, esr, and bulged tops, outside the circuit before ordering / changing them ?
Normally you isolate the sections, remove the mains capacitors for tests, test the rectifier bridge forward and backwards and you test the continuity of the transformer primary sides and secondary sides, you may have an blown thermal fuse in it.
The x-former secondary ohms values seems good, i do hope you take measurements in AC before the rectifier bridge and DC after the rectifier bridge ??
To me your x-former main ac voltage should be between the gray and brown colored wires, you see an capacitor between theses pins, i think the green 117.7v value between yellow and brown is not okay, it may simply an induced voltage in the wiring ... you have voltages taps to select the main ac voltages, you check continuity between all the primary wirings.
