Electric Blanket Repair

[David Roper]

This is the type I grew up with:

Parents and grandparents both had several blankets using that type of control. Note the power plug. The absence of a large flared surface at the point the blades come through dates it to sometime prior to the mid 1970s; anything later would have a more modern plug. Also, a polarized plug almost definitely means 70s or later.

A notable exception to that polarization rule is Sears...TVs I have a 1963 roundy and a late 60's Japanese portable, and both have polarized cords and interlocks.

Um, roundy electric blanket? Never seen one. Always rectangular in shape.

The OP was talking about electric blanket control plugs, not TVs....
