notes: label: Description (Brief)
content: A 5-pin plastic base (1 long pin with plastic tip) with center post, top contact, metal envelope with adjustable plates on the left side, adjustable post on the right. Paper label: "Raytheon / JAN-CRP / 2K25 / Made in U.S.A."; stamped: "[eagle logo] / 841 / J13104". Donor’s card reads: “Velocity variation oscillator made by Raytheon. The 2-K-25 is a mechanically tuned velocity variation oscillator of the single-cavity reflex type designed for continuous wave operation in the 8500 to 9660 megacycle range, with an output of 30 mW. Particularly well suited for use as a local oscillator in microwave receivers, as a local oscillator in spectrum analyzers as a microwave source for test purposes. Heater: 6.3 volts at .44 ampere. Resonator voltage 330 DC, reflector voltage 0 to -400 DC. Guaranteed minimum life 500 ours. Coaxial type output to couple into a standard 1’ x .5” wave guide through a suitable transducer.” See also: https://www.radiomuseum.org/tubes/tube_2k25.html.
