Tubes, brackets, and insulator neck profiles vary by catalog series even when voltage and amp labels look similar on paper.<\/p>\n<p style=\"margin:0 0 16px;line-height:1.7\">Wrong-family spares show up as bent hinge ears, mismatched contact gaps, or insulators that mount but do not meet the owner\u2019s creepage record.
