Running spares listed above are stored in designated positions on the inside cover and chassis (figs. 1 and 8 ) of the tube tester. 6. Description of Test Set, Electron Tube TV-2(*)/U (fig. 1) a. Test Set, Electron Tube TV-2(*)/U (tube tester) is housed in a carrying case equipped with a carrying handle, two electrical clips for connection to the top cap of a tube under test, operating and spare tubes, fuses, indicating lamps, and miniature tube pin straighteners. The cover is secured to the case by luggage-type fasteners. Power cord brackets and a dummy power cord recep- tacle on the panel are used to secure and store the power cable. Tube test data is given on a roll chart; the roll chart case is mounted inside the cover of the tube tester. A condensed summary of operating instructions also is mounted inside the cover of the tube tester. The cover is hinged by slip hinges and can be removed from the case. Two handles attached to the panel permit easy lifting of the tube tester from the case. b. All indicating meters, switches, controls, and tube test sockets are located on the panel of the equipment. The necessary data for setting and operating the controls to test the various tube types are contained in the tube test data roll chart (a above). Two electrical clips (A and B, fig. 3) provide connection to external caps of tubes as reqired. One end of the power cord is perma- nently attached to the panel; the other end terminates in a male plug. 7. Differences in Models Test Sets, Electron Tube TV-2/U, TV-2A/U, and TV-2B/U are similar in purpose, operation, and appearance. On some equip
