CRYSTAL_CONTROLLED_BLOCKING_OSCILLATOR
Used for recording 50-kc reference base on magnetic tape in 10-channel instrumentation system. Circuit is ordinary plate-to-cathode coupled blocking oscillator with crystal substituted for capacitor. If free-running frequency (without crystal) is lower than crystal frequency by no more than 40%, oscillator locks to crystal frequency.-P. S.
