So I built a kit that uses an electrostatic deflection CRT for the
display. It all turned out very well except the display is much more
in focus on one side of the screen.
The CRT I am using is a Russian 5LO38i. The Heater voltage for this
CRT is 5.7 to 6.9 volts and I measure only 5.1 volts.
I'm not sure how the voltage for the heater or how any of the other
voltages might affect the sharpness.
The specs for the Russian CRT has the first anode voltage at 550
volts max and the second anode voltage max at 1100 volts max. But I
measure only 250 volts for each. Could this be why the focus is not
even?
Anyway, thanks for any help.
