A METHOD FOR FREQUENCY TUNING THE CRYSTAL OF PIEZOELECTRIC CRYSTAL OSCILLATORS COMPRISING, MOUNTING A CRYSTAL IN A SEALED HOUSING, APPLYING A CURRENT TO SAID CRYSTAL TO ADJUST SAID CRYSTAL TO A PREVIOUSLY CALCUALTED FREQUENCY, PROVIDING A SOURCE OF VAPORIZABLE METALLIC MATERIAL IN HEAT CONDUCTING RELATING RELATIONSHIP IN SAID HOUSING IN AN OPTIMUM SPOT POSITION RELATIVE TO THE CRYSTAL TO ALTER SAID CRYSTAL FREQUENCY WHEN EVAPORATED DURING TUNING OF SAID CRYSTAL AND EVAPORATING SAID METALLIC MATERIAL BY CONDUCTION OF HEAT THROUGH SAID HOUSING.
