Whats the best way to test the output of a transformer? Can I just use a multimeter? Answered
I have a guitar amp that I want to make portable but the transformer isn't labeled, so I don't know what kind a batteries I need. Is the multimeter a valid option, or is there another way to find out how much power is coming out of It? Unless you can identify the writing on the back of the transformer (which I already googled).
