In 1922 three men, all expert glass blowers, opened one of the most successful independant lamp plants in the country. With prosperity, both General Electric and Westinghouse became interested in the businees. Eventually General Electric bought the business. George Coby, Ely Egnatoff and Willian Cepek next ventured into the Radio Tube Business and founded the first indepenant radio tube company in this part of the country. 5

In 1928 the executive officers of the Triad Tube Company of Pawtucker, RI were George Coby, president, Ely Egnatoff (one of the principals of the CeCo tube company), treasurer, Harry Steinle, vice-president and general manager, and Willian Cepek (another principal of the CeCo tube company), secretary. At that time they were the largest indepentant tube factory in the Country.

The engineering staff included S U Marie, PHD, Roger Williams, PHD, A S Friedman, BS, and Gregory Ryisky, EE ME, in addition to graduates of the foremost technical and engineering schools in the country. 2

The connection with CeCo tubes comes from an agreement that Egnatoff and Cepek, made when they sold the company, to not manufacture tubes for one year. So, they moved across the river to Pawtucket and manufactured Triad Pens, which were triangular pens that wouldn't roll off the table. Apparently, the lure of radio tubes was too much because in June 1929, Triad announced their new line of radio tubes in a distinctive triangular box. Immediately successful, $1,000,000 in sales was reached in the first year. 3

Also in 1929, Triad made a deal with RCA to build tubes under their present and future patents. 8

In 1930 production was on the increase in the new Triad plant in Pawtucket, RI. According to president George Coby more than 600 people were on the payroll. The factory has increased floor space and mechanical facilities. Reactions at Radio trade shows in New York, Chicago, Boston and Philadelphia have proved to be hibhly encouraging. 4

In June of 1965 we find an article in The Miami News of The Triad Tube Corporations moving into a new 15,000 square foot plant and headquarters in Sunshine State Industrial Park in North Dade. The company at that time is described as an electronics wholesaler distributing vacuum tubes for radio and television sets, selling through discount chain stores and for the industrial market. Their president Frederick M Bender said they moved from Hialeah to expand their facilities to meet the firms goal to get "at least one per cent of the annual 400 milion dollar vacuum tube replacement market." 9

On January 1st 1975, in the state of Florida the Triad Tube Corporation was setup. Its location was 71 NW 25th Street in Miami Florida. President, Director was William S Kirk, Director Susan D Kirk, Director Joseph D Weatherby. The company was involuntarily desolved in April, 25th 1978. 7
