When the tube is operated at 100 percent of maximum rated anode dissipation at an incoming air temperature of 25C maximum, a minimum airflow of 5.6 cubic feet per minute (cfm) at sea level shall pass through the anode cooler. The static pressure drop
20、across the anode cooler at this flow is approximately 0.26 inch of water. If the socket on Drawing 246-JAN (see note 13) is used, an incoming airflow of 5.6 cfm to the grid end of the socket is required. At this flow of 5.6 cfm, the static pressure drop directly across the tube and socket is approxi
21、mately 0.60 inch of water. This pressure drop varies with the amount of escaping air and with the shape and construction of the air director. The airflow rating applies at bias voltages less than 100 volts and frequencies less than 500 MHz. Air cooling of the tube shall be increased with increased n
22、egative grid bias, increased incoming air temperatures, or increased frequency of operation, or a combination. In all cases of operation, a socket which provides forced-air cooling of the base shall be used and maximum seal and radiator temperature ratings shall not be exceeded. The airflow shall be
23、 applied before or simultaneously with electrode voltages, and may be removed simultaneously with them.

24、may be obtained by adjusting the heater voltage in accordance with the application. A table of heater voltage verse frequency is presented as a guide. Frequency (MHz) Ef (V ac) Up to 300 6.00 301 to 400 5.75 401 to 500 5.50 3. In all cases of electrical tests involving application of heater voltage,
25、 the socket on Drawing 246-JAN (see note 13) shall be used. An incoming airflow of 6.0 cfm maximum to the grid end of the socket is permitted. 4. An infinite baffle system as shown on figure 2, or equal, with an airflow of 5.6 cfm at sea level shall be used. The static pressure drop is measured acro
26、ss the tube and socket. 5. The forced-cooling test shall be made as follows: At an ambient temperature of 25 C, both the base and the anode shall be cooled by applying an airflow of 5.6 cfm maximum, at sea level from a single source using the infinite baffle system as shown on figure 2, or equal. At
27、 the specified test conditions, the anode core temperature, the anode seal temperature, and the base seal temperature shall not exceed the specified limits. All temperatures shall be measured by means of thermocouples located as follows: Anode core: This thermocouple shall be embedded in the top of
28、the cooler, with the anode dome removed, if necessary, by means of drilling a small hole, shallow enough so that the tube vacuum shall not be lost, placing the welded thermocouple junction therein, and then bending the edges of the hole in order to hold the thermocouple firmly in place. Anode seal:
29、This thermocouple shall be attached, using any appropriate material, to the surface of the metal immediately above metal-to-dielectric seal. Base seal: This thermocouple shall be attached, using any appropriate material, to the surface of the metal immediately adjacent to the base dielectric materia
30、l and at the immediate periphery of the dielectric material. In all cases, good electrical continuity between the thermocouple and the metal area in close proximity must be demonstrated before the cooling test can be performed. 6. This is a destructive test. Operate the tube in an upright position.
31、Preheat the tube at specified test conditions for 1 minute. Remove airflow for 100 seconds. Restore airflow and after 1 minute perform the total grid current test. Any tube which evidences a short or open circuit during this test will be considered a failure. 7. The maximum value of the voltage appl
32、ied to the anode and grids shall not exceed 900 volts. The pulse duration measured at 5 percent of the maximum value shall be not less than 3 microseconds (s). At 50 percent amplitude, the duration shall be less than 2 s. The applied voltage shall have a maximum repetition rate such that the duty cy
33、cle, based on the pulse length measured at 50 percent amplitude, shall not exceed 0.0002 (0.02 percent). An alternate pulsing emission test may be used with the following conditions and limits: Conditions Parameter Minimum Maximum is = 30 a , eb = ec1 = ec2 etd - - - 850 v For life-test end points,

This test is to be the first test performed at the conclusion of the holding period. 9. Circuit and cavity
35、shall be in accordance with Drawing 223-JAN (see note 13). 10. This test shall be made a minimum of 30 minutes after Ef is turned off. Rated airflow shall be maintained during the 30-minute interval. Measurement to be made with General Radio Megometer Model No. 1862C, or equivalent. Unused elements
36、shall be left floating. 11. Tube type 7035 has been deleted from this tube specification sheet : use MIL-PRF-1/1331, type 7609. 12.

Pin alignment shall be checked by means of JEDEC gage GB8-3. Dimensions of control-grid contact shall be inspected by means of gages specified on Drawing 246-J
38、AN (see note 13) and shall be conformance inspection, part 2. 2. Alignment of anode, screen-grid, and control- grid contact surfaces shall be determined by means of gage specified on Drawing 168-JAN (see note 13). Conformance inspection, part 2, shall apply. 3. Air system socket shall be as specifie
39、d on Drawing 246-JAN (see note 13). 4. Location of guide lug of control-grid contact may be referenced by a notch or arrow on the anode radiator in the position shown. 5. Anode clamping shall be confined to the anode radiator. 6. Dome contour shall be such that it will be contained within crosshatch
40、ed area of template shown on figure 3. Optical comparator techniques are normally used for this purpose. 7. Perform on a sample of 10 tubes from the first production lot of each year, with one failure allowed. In case of a sample failure, the failing dimension(s) shall become part of conformance ins
