[Elecraft] Looking for source for wire and fuses

[Stuart Rohre]

Usually, traditional brown zip cord has one smooth insulated conductor, and 
the other conductor has a rib running axially, or a series of markings to 
allow one to "polarize" the use of the brown cord.  In the old days, we made 
the conductor having the rib along its entire length the neutral conductor 
for brown zip AC cords.  You could even determine the "polarity" by feeling 
the cord in the dark for the prominently ribbed ones.
