PREFERRED_PARALLEL_TRIGGERED_BLOCKING_OSCILLATOR_BELOW_2000_PPS
Produces synchronizing impulses between 0.2 and 7 microsec wide at rates of 200 to 2,000 pps. One triode section is used as trigger amplifier to prevent triode blocking oscillator from reacting on trigger source. R6 and R7 are 100 ohms for 5814A and 150 ohms for 6111. R8 should be maximum that will just suppress ringing. Requires positive input trigger and gives choice of output polarities at the four output terminals.-NBS, Handbook Preferred Circuits Navy Aeronautical Electronic Equipment, Vol. I, Electron Tube Circuits, 1963, PC 46, p 46-2.
