Reinartz crystal oscillator

Reinartz crystal oscillator

[′rīn‚ärts ′krist·əl ′äs·ə‚lād·ər]
(electronics)
Crystal-controlled vacuum-tube oscillator in which the crystal current is kept low by placing a resonant circuit in the cathode lead tuned to half the crystal frequency; the resulting regeneration at the crystal frequency improves efficiency without the danger of uncontrollable oscillation at other frequencies.
