tor C charging voltage of about 160V. Shutdown, reed contacts open, since the larger capacity C, and its main tributary discharge has been cut off, so that the CRT cathode voltage will be retained for a period of time to cut an electron beam to achieve the purpose of eliminating the highlights. Reed should be added around the outside of a coil, the coil frame including enamelled with 0.1MM tightly wound 5200 turns coil end of the ground, and the other termination power + 12V.
