CV228 Heil tube, for use as an oscillator in the frequency range 4.4 to 4.85GHz. With a cathode current of 65mA, the minimum output at 4.65GHz is 450mW.
Also known as V246A/1K.
|The CV228 pictured came with a test certificate titled 'Broadcasting stations - transmitting tube record'. This shows the serial number of this valve to be LYQ5G and the first test date is 11/2/54, followed by 14/7/74. The tube is new and presumably never used other than being tested. Unfortunately because of this, the interesting area of the card ("Tube employed as") is blank!|
