[Boatanchors] Article on changing from 2 to 3 wire power cords

[wb3fau55 at neo.rr.com]

This is as safe as you wish to make it. Knob and tube wiring is safe
as long as you do not disturb it. Polarized 2 wire plugs are a help.
Lot of new stuff sold that way. New hair dryers have GFI protection in
the cords. Boatanchor radios are usually metal cabinets and need 3
wire cords. also good HQ ceramic caps on each wire to ground. GFIs
that trip, tell you there is a problem. 73 Russ.

Just as a data point, the house I grew up in was built around 1952 and
used the two equally sized outlets. Seems the addition, added on in or
about 1961 used the three pronged outlets. I also remember buying
lamps in 1977 that had two equally sized prongs, something you won't
see today.
