My CE-5 has the same problem.
I am thinking about how way back in my early TV servicing days,
some televisions used an oscilloscope type CRT - used deflection
plates for the internal sweep instead of the later used external
magnetic deflection circuitry.
Those older TV's, as I vaguely remember, had a power supply problem.
Most used a series of 1 megohm resistors in a voltage divider for the
CRT intensity and focus circuitry. When those original factory
installed resistors drifted in value, the CRT intensity suffered.
My CE-5 has another problem, some of the frequency readout lamps are
burnt out. One of the these fine days, the CE-5 will be
disassembled slightly to replace those lamps and the CRT power
supply problem will get a serious look too.
Do you have manuals for the basic CE-5 and its plugin modules?
