| 1 | For operation in a 525-line, 30 fram system, the duty cycle of the voltage pulse must not exceed 15% of one scanning cycle. |
| 2 | In stages operating with grid leak bias, an adequate cathode bias resistor or other suitable means is required to protect the tube in the absence of excitation. |
