I-177 Data Book from Bigelow Electronics (July 18, 1954) An interesting thing that may come in handy to certain people, is that the settings data between the I-177 series military tube tester and the Hickok commercial models AC-51, 51X, T53, 510X, 530, 531, 540, 550X, 560, 560SPL, and KS9237 appea

28、 CAUTION: After testing tubes, always set all controls to off or saftey positions as indicated in the following table. Tubes may be burned out if inserted in test sockets before the controls have been properly set. Saftey Position Extreme counterclockwise OFF 1 Control POWER SHORT-TUBE TEST LINE ADJ

To adjust the line voltage, press and hold down the LINE TEST button and turn the LINE ADJUSTMENT knob until the meter pointer is exactly at the LINE TEST position (at 1,500, not at the ? on the scale)

34、; then release the LINE TEST button. k. After allowing at least 30 seconds for the tube to warm up, turn the SHORT-TUBE TEST switch slowly from position plate top cap of the tube to the upper left contact of the 6-pin socket C with the 12-inch lead having a clip and bananna plug. For some tube listi

Set the POWER switch to the ON position. to the next, since this is due to the charging of a capacitor in

36、 the lamp circuit. NOTE: Before discarding the tube, refer to the Notations column of the test data for the listing of that tube to see if the tube being tested normally appears to be shorted on certain postitons of the switch. Thus, for the 1LN5, the notation Shorts on 4 and 5 in the Notations colu

If the lamp continuously or glows during tapping in any of the five positions, the tube contains shorted elect

Press the button indicated in the Press column of the test data, and read the meter on the RED-GREEN scale. a. Test the tube for shorts by following the complete

41、 procedure listed above. If the tube is shorted, discard it without making further tests. b. If the tube is not shorted, turn the SHORT-TUBE TEST switch to the TUBE TEST position. Do not change any of the other controls used for the shorts test. good. Good diode sections may read in the portion of t

42、he RED scale marked DIODES O.K. Only diodes reading to the left of this section (to the left of A in REPLACE on the scale) should be considered defective. CAUTION: Do not press the red AMPL.TEST button while testing rectifier tubes. When testing small diodes, do not press either the AMPL.TEST or a R

43、ECTIFIER TEST button, because the high voltagw would damage the delicate g. Normally, if the pointer stops in the GREEN sector the tube is good; if in the RED sector, the tube is defective and should be discarded. If the pointer stops in the ? sector, the tube is usable for a few more hours but shou

If a tube is listed two or more times in the test data, it has two of more sections requiring individual tests,

46、or has two input grids (for example, 6A8 pentagrid converter) requiring separate dynamic tests. i. Remove the tube from the socket after the first test is completed. Then repeat the quality test for each additional discard it without making further tests. b. If the tube is not shorted, turn the SHOR
