"If you check the schematics, the 270V is made/comes from the power supply...BUT the 60V enable relay (feeds the voltage divider and read on the front panel) is on the PA board... "
May I suggest that you look at KPA Power Supply Schematic sheet 1 of 2 and locate relay K1 (60 V Enable) which is controlled by the interlock switch and signal 60 V ENBL. How is 270 V produced if this relay is open? How is 270 v produced if 60 V is not present? I do not think it a coincidence that the OP has lost 270 V and 60 V. I suspect a common cause.
