CFTH Thomson-Houston
This 50,000 watt AM shortwave broadcast tube operates 2 to 30 MHz. This massive tube is 10 x 17 inches and weighs 44 lbs. We suspect ½ to ¾ of the weight is in copper [with a scrap value=$110 to $165!]. This vapor cooled triode TH-477 variant was manufactured in France in 1956 for the Voice of America Kavala relay. Includes photo copies of 3 page spec sheet and series ad.
Because of the weight U.S. shipping will be $100-$150.
