as follows: | It was originally designed to use the 5XP CRT, | ||
which has 38V/cm vertical deflection sensitivity when operated with 24kV acceleration voltage. | |||
The vertical sensitivity at the input connector is 0.1V/cm. So the voltage gain is 380. | |||
For 4cm deflection, a 152-volt differential output swing is required. | |||
The vertical signal path is as follows: | |||
