Vintage General Electric JAN-CG-2C46 "lighthouse" disc-seal UHF triode. The base is printed JAN-CG-2C46 with the GE monogram; the bottom of the octal base carries a printed instruction partly worn. Comes in a plain white box hand-marked 2C46. Untested; sold as found. The base shows handling wear and the glass has light dust and marks.

The 2C46 is a military UHF oscillator tube — JAN marks it as a Joint Army-Navy standard part, and the CG code is General Electric's JAN maker code. A good piece for military-electronics and radar/IFF collectors or tube collectors filling out lighthouse types.
