Radio transmitting tube
notes: label: Description (Brief)
content: Unit appears to be water cooled. No extant maker's markings. A band around the middle of the cooling jacket may be a shadow from a label. A glass tube with two lead wires mounted onto a black painted flange. The flange is set on a plated non-ferrous cooling jacket with a rubber gasket. Four bolts pass through the flange and allow the tube to be mounted in the transmitter. The jacket has two metal tubes projecting to the side, one for water intake and one for export. The tube is bell-shaped with the open end up. A tip is on the top. One stranded copper conductor is connected to a lead wire and has a glass sleeve insulator. The other conductor is missing and appears to have broken off of the other lead wire.
