[AT] Project Updates '49 A, '51 A, and '47 B (STEVE ALLEN)

[Howard Pletcher]

Resistive wires are used to help eliminate radio frequency interference
(static) in radios and other equipment. They would make no difference in
the current flowing in the primary side of the system which the ballast
resistor does
