This negative pulse is applied to a joaonostaLle oultivibrator V^,V3 whicn generates the 4000 micro-second negative gate piilse shown in (b) above. This type of circuit is used because it is less susceptible to ciianges aiopiitude caused bj oi' gate duration and tube changes tiian are cathode coupled circuits.
