Frequency of free.-running twin-phantastron oscillator V3-V4 varies with controlled voltage ES (upper right). V5 gates starting pulses to phantastron when-ever it fails to oscillate. Used to generate train of pulses that continues in synchronism with incoming video data even when sync pulse is missing or below noise level-W. C. Whitworth, Plate Voltage Control of Phantrastron Frequency, Electronics, 34:6, p 73-74.
