8 Channel Amplifier
Hello I am preparing an 8 channel amplifier using the TDA2050 chips. How does one
properly calculate the VA for the transformer? This will also have to run at 4 and 8 ohms so I assuming that I will need to go with around a 15volt secondary to get 18VDC? Thanks for your replies |

Use a transformer rating that is bigger than or equal to the combined output power of the amplifiers.
And yes, 15 V is okay.
