    Hello Fellow Ham radio

    I just purchased a SB 220 (I had before!),

    I need to wire for 120V...I can't seem to find the jumper settings...

    Currently wired for 220V

    Look forward to your response..

    Be careful using it on 120V, it can draw more line current than a 15A household branch can deliver.
