Hi there,

I have this 100MHz 2 Ch analog scope which is facing out of focus problem.
I have checked the voltage at the CRT as shown below:-

VK = -2461V @ heater and cathode
Vg = -2535V @ control grid
Vf = +328V to +383V @ focus grid when I adjusted focus knob.

Is the focus voltage normal? If not, what's the correct value?

Thank you for your advice in advance.
