Re: 5116+5D10 intensity problem
When the Anode voltage on the CRT is lower than it is supposed totoggle quoted messageShow quoted text
be, the electrons in the beam travel proportionately slower than
they should. Because they are slower, they spend a longer amount
of time to passing between the deflection plates. This means
longer time means that the force the electric field between the
plates applies to the electrons, has a longer time to work at
deflecting the electron beam. Which further means the electron
beam will be deflected more than it would at the proper voltage.
What you should take away from this is: If the anode voltage is
low, everything on the CRT screen will be expanded (magnified) out
much larger than it should be.
That your readout is expanded outside of the screen is nearly
perfect proof that your anode voltage is low. You can guestimate
how low by how much the expansion is. But it is most definitely
lower than it should be.
