Station Information

NIST radio station WWVB is located on the same site as NIST HF radio station WWV near Fort Collins, Colorado. The WWVB broadcasts are used by millions of people throughout North America to synchronize consumer electronic products like wall clocks, clock radios and wristwatches. In addition, WWVB may be used in other consumer timekeeping applications, such as appliances, cameras, and irrigation controllers, as well as in high level applications such as accurate time synchronization.

Loctal tubes had shorter connecting lengths between the socket pins and the internal elements than did their octal counterparts. This allowed them to operate at higher frequencies than octal tubes. The advent of miniature “all-glass” seven- and nine-pin tubes overtook both octals and loctals, so the loctal’s higher-frequency potential was never fully exploited.

Loctal tube type numbers in the USA typically begin with “7” (for 6.3-volt types) or “14” for 12.6-volt types. This was fudged by specifying the heater voltage as nominally 7 or 14 volts so that the tube nomenclature fitted.

Although Loveless went ahead and sang in the television special, her manager canceled all of her tour dates for the remainder of 1992. On October 21, Loveless had corrective throat surgery. For the next nine weeks, she could neither sing nor talk.

The amplifier was one side of the desk, the amplifier was sold separate from the desk, the desk was optional. For its time, 1956, it had TV suppression, would function on 115 or 230 volts, the amplifier was 400 lbs and the optional desk was another 155 lbs… it sold for 1595.00, desk sold for 132.00. The desk came in 2 models depending on which side of the desk you wanted the amp on…
