WCBS newsmen report on the 1965 blackout as the staff looks on.
On Thursday, Aug. 14, 2003, many cities on the east coast and in the
Midwest lost power due to a severe blackout. Although this was not the
first time a blackout ever occurred, it was monumental in that so many
cities were affected. For more than two business days, many companies
could not function and people were stuck without air conditioning or
electricity in the stifling heat. While the cause of this blackout is
still being investigated, we can learn from past blackouts what to
watch out for and take caution against.
In Nov. 9, 1965, a blackout affected the city of Ontario, Canada. It
took six days for Federal Power Commission investigators to locate the
cause. They found a single faulty relay at the Sir Adam Beck Station
no. 2, which caused a key transmission line to disconnect (open). This
small failure triggered a sequence of escalating line overloads that
quickly raced down the main trunk lines of the grid, separating major
generation sources from load centers and weakening the entire system
with each subsequent separation. As town after town went dark
throughout the northeast, power plants in the New York City area
automatically shut themselves off to prevent the surging grid from
overloading their turbines. Within a quarter of an hour the entire
CANUSE area was down. Investigators referred to the 1965 blackout as a
cascade effect—much like a row of dominoes falling one after
Twelve years later, another blackout took place in New York City on
a hot and muggy night. Fortunately, this blackout did not have as
severe an effect on radio stations and broadcasters.

In 1941, RCA designed the 76-B2 to provide "a flexible speech input
system for maximum economy." It provided all the amplifying and control
equipment required to successfully handle two studios, an announce
booth microphone, a control-room announce microphone, two transcription
turntables and six remote lines. Full facilities were provided for
simultaneously auditioning and broadcasting from any combination of the
studios, turntables or remote lines.
The amplifying and control equipment was mounted in a single metal
console and the power supplies were located in a metal box designed for
wall mounting. An override-record switch was provided, which permited
the remote operator to call in on any of the six remote lines and
override the program on the control room speaker. Key switches are
interlocked to disconnect the studio loudspeakers and operate "On Air"
light relays. A three-position key switch in the input of the fourth
preamplifier permits it to operate from a microphone in the studio,
announce booth or local control room. Additional push-key sets provide
circuits for feeding cue to remote lines and for bringing in monitoring
circuits such as transmitter or master control outputs. The console was
constructed of metal with wooden style plates on each end.
