Triad Television & Mfg. Co.
Pawtucket, Rhode Island

According to Tyne's "Sage of the Vacuum Tube", page 364, this manufacturer was licensed by RCA.

See also the Roytron tube brand.

Other known brands are All Wave, Diktator, Long Life, Nu Star, Real Tone and Royal. These tubes were made in the early 1930's and used different coloured boxes. The print style on the boxes was the same for each but differed from the Roytron.

Founded: 1929

The journal "Radio Broadcast", issue May 1929 tells on page 45: "Another vacuum-tube manufacturer has entered the field. The new company will be known as the Triad Mfg. Co. with headquarters at Pawtucket, R.I. George Goby is president, Ely Egnatoff, treasurer, H. H. Steinle, vice-president and general sales manager, and William Cepak, secretary. Officers of the company have long been associated with the tube industry. The new company will make, in addition to a standard line of radio tubes, photo-electrical cells. Distribution of the Triad line will be through franchised jobbers only."

In 1935 Triad introduced a line of metal vacuum tubes with octal base in answer to the GE-RCA metal line. The early release of Triad line, with MG suffixes, included 13 types, all characterized by glass bulb inside a metal enelope.
