That is considerably anecdotal, but some server power provides is not going to get started when powered having a modified sq. wave power supply..
Dirty power demonstrates up as a portion of the output sign, determined by how much responses the amplifier has.¹ This is one of the two key will cause of line hum in old amps.²
