Can anyone please tell me if it's OK to use a power brick/supply that's sold as an LED power supply to power an amplifier? I need a 230VAC to 24VDC, 4A power supply to power an amplifier and the best value switching power supplies I've seen have been sold on LED lighting websites as LED driver power supplies. I should be OK as long as I select the correct output voltage and sufficient current output rating for my application, right? Thanks.
