Antique Radio
(The author is not responsible for any injury or death that may occur due to working on antique radio equipment. Antique radios are dangerous because of the high voltages inside of the radio equipment. Do not work on antique radios unless you have proper training or experience. Serious injury or death can occur. These briefings are for reference only.)
