Before you write me a question, read this entire description.

Approximately 20 lb before packaging.

7" x 12" x 5" (H x W x D)

*This gap will have to be disassembled for shipping. If you're not good at putting together puzzles then this is not the item for you.

This is a recreation using an original frame of the AMRAD TYPE G 1 kilowatt quenched Gap with much-heavier-copper-plates than originally spec'd. This has not been tested but could probably handle more than 2.5 KW. The questionable part is the insulators which are mica discs. The overall breakdown voltage is unknown as **this item is untested.** That would be up to you the wireless experimenter should you choose to go rogue and become a Pirate Radio operator risking the FCC knocking on your door.** It's beautiful, as is, but I am sure that this restoration/recreation/reconstruction has room for refinement. We in no way, shape, or form condone the use of this item for any type of radio transmission. **This is a museum piece and not for practical use.**

The original gap plates have been lost to time over the last hundred plus years and that is the reason why it was refined into an example of what the original appearance would have been.

The American Radio and Research Corporation (AMRAD)

Founded in 1915 by Tufts alumnus Harold J. Power, A1914, the American Radio and Research Corporation (AMRAD) was a pioneering force in the early days of radio technology.

AMRAD's early years were marked by significant achievements. The company initially operated from a laboratory behind West Hall at Tufts University, utilizing a 304-foot radio tower to broadcast signals. AMRAD's station, initially assigned the call letters 1XE and later WGI, quickly became one of the most popular in the Boston area.

Beyond broadcasting, AMRAD also focused on manufacturing radio parts and equipment. The company played a crucial role during World War I, developing and producing transmitters, receivers, and even an advanced submarine detection system for the U.S. military.

Post-war challenges led to financial difficulties for AMRAD. Despite efforts to expand production capabilities with a new manufacturing plant, the company was unable to maintain profitability. In 1925, Power was forced to declare bankruptcy.

In 1930, Power merged the remaining assets of AMRAD with Motorola. Tufts University acquired the local AMRAD facilities, converting the broadcasting laboratory into North Hall and the manufacturing plant into the Hooper Laboratory, later renamed Halligan Hall.

AMRAD's legacy lives on through its contributions to the development of radio technology and its impact on the early days of broadcasting.
