Aside from being unavailable, the schematic won't tell you.

Behringer schematics do not usually include the transformer, and the voltages are not specified anyway. On the schematic, the AC is rectified and filtered and called out as "V+" or "V-", or "VCC+" and VCC-".

If the amp has 15v regulator ICs, then you know the preamp is running on +/-15. But for the main voltage, look at the filter cap voltage, and decide from that. Look at the output powr amp IC and consider its power supply specifications. SO if the caps are 35v, then I'd guess the V+ is 25-30vDC.

Calculare what AC voltages would be needed to provide the DC you need.
