Fivre was the largest all-Italian company, founded in 1932 in Pavia by Magneti Marelli to produce vacuum tubes under Radiotron license. For a while their tube supplies to the parent company, Marelli, were characterized by distinctive violet-glass bulbs. In their ads they evidenced the equivalence of their tubes with those manufactured in the United States by RCA. ‘RCA – FIVRE: From America to Italy, different brands but the same quality’ said an ad from a 1934 magazine.
Fivre produced some of the best sounding audio valves such as the classic 2A3
6F6GT Fivre Italian made identical to RCA item. This 6F6GT is an audio output pentode valve that was designed in the mid-1930 and used in many Wurlitzer vintage jukeboxes. These valves were available first in a metal case 6F6, then in large classic glass envelopes (6F6G), and then later in tubular GT shape hence 6F6GT and this valve is the straight sided item.
The valve had a maximum rating of 315 Volts on the anodes and operated in class A1 push pull; this valve type would generate 10 Watts with 3% distortion. This type was obsolete by the 1960s as many manufactures moved to 6V6GT so is now very hard to find.
These valves excluding the base pins are 80 mm tall. Ideal for restoration of vintage juke boxes
