If you want to get the perfect sound out of your amplifier, you need to tune it with a multimeter. This guide will show you how to do just that.
First, set your multimeter to the AC voltage range. Then, plug it into the wall outlet and turn on your amplifier. Next, slowly turn up the volume on your amplifier until you reach the desired level. Finally, check the reading on your multimeter. If it is within the acceptable range, then your amplifier is properly tuned!
