Toroidal transformer 2 x 45Vac - 230Vac/50Hz
Using this transformer in a traditionally configured power supply will give rail voltages around +/-63V unloaded. A
rail voltage of 63V will give a normal configured amplifier an output power around 200W at 8 Ω and 320W at 4 Ω.
Under load the transformer voltage will be lower depending upon the specific load and therefore you will not get the thereoratical
calculated output power of 253W at 8 Ω and 506W at 4 Ω. There are also losses at the bridge rectifier, amplifier
module and to some extend in the cables.
