ABSTRACT:
For the process of epilation by electrocogulation, a solid state circuit for the production of high frequency waves at predetermined timed intervals and intensities, the wave produced having slow rise and decay periods. An integrated circuit charges a timing capacitor which directs an amplification circuit consisting of transistors to direct intermittently timed wave-producing regulated voltage to a probe at the end of a coaxial cable having a predetermined impedance. An overrated transistor in an output circuit feeding the wave producing probe is capable of withstanding reflected and standing waves produced at said probe.
