سؤال: Hi how many ampere of transformer do I need to power up this 300 watt amplifier board? Is it a true 300 watt rms?

sps Use a transformer rated at 250 VA and with 2x24 V AC secondary windings. The maximum RMS power would be 2x100 Wrms for 4Ω speakers, 2x75 for 6Ω speakers, 2x50 Wrms for 8Ω speakers and 2x25 Wrms for 16Ω speakers. Keep in mind that these are the maximum theoretically possible power output values using the right sized power transformer (250 VA - 2x24 V AC) and the THD values are at their maximum and audible! levels.
