By the look of the transformer T337, it is a single phase transformer, there is a primary connection for 115v between 0VAC & 115VAC.
For 230 connection the connect 1 to 6 and connect 5 to 9 with the supply to these two connections
The secondaries show paralleled up , if you have a common DC power supply for all the amps, this is where the secondary should be connected to.
Measure your DC to the amplifiers.
