315_KC_CRYSTAL_OSCILLATOR
Provides sync signals for tv camera sweeps. Crystal vibrates in lowest-frequency natural mode of long thin bars, resulting in high impedance and difficulty in exciting crystal, and making it necessary to use two transistors in symmetrical collector-coupled mvbr oscillator.-D.
