advantage of such common emitter --- common emitter connection is high working
frequency to achieve the purpose of broadband amplification. At last, V902, V912 and
V922 collectors output RGB signals of around 130Vp-p, which are directly coupled to
RGB cathodes of the kinescope via R917, R927 and R937 to control the size of RGB
electron beams.
