Carver M 400t operating voltage
How can I change the operating voltage of my amplifier Carver M 400t
from 110 v to 220v, because I buy from USA that 100v operating voltage and
now I used in Indonesia that use 220 v operating voltage.
And why the transformer is buzzing ?
Who can help me to answer my question above.
