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...

The 60V relay does not close if 270V is missing?" Assume 60 V Enable relay K1 is not closed. How would 270 V be produced? The secondary winding of T1 is open circuit.
