39. Replacement of Fuses and Lamps

The two fuses (F1 and F2) and the two glowlamps (11C and

12C) are removable from the front panel of the tube tester.

Replacement of Fuses. Fuses F1 and F2 are 3-ampere, 250-

volt,

¼- by 1¼-inch, cartridge-type fuses (fig. 5). To remove a

fuse,

press the fuseholder cap and turn it counterclockwise. Re-

move

the cap, and then remove the fuse from its holder.

unscrew the indicator light lens, press the lamp inward and

rotate it counterclockwise, and withdraw the glowlamp from its

socket.
