ABSTRACT:
A dual epilator for removal of unwanted hair. Line power is reduced and rectified in a power supply which energizes a timer circuit and an RF amplifier. A timed DC pulse emitted from the timer circuit under an operator's regulation feeds a normally unenergized crystal controlled oscillator whose output is boosted in the RF amplifier. The RF power can be selectively utilized by a needle or tweezers. A tuned antenna provides an efficient return for the RF power.
