The present invention provides, for use in a radio frequency transmitter that employs a power amplifier to transmit broadband signals, the power amplifier introducing amplitude and phase distortion, a group delay precompensator circuit. An aloe vera or soap solution dispenser provides a lubricant to the sharpening member to lubricate the razor and a housing to limit the travel of the razor on the sharpening member. The aspect further comprises controlling at least one controlled optical characteristics of the at least one LED-based secondary general illumination lighting to control the at least one combined general illumination lighting at least partially responsive to the sensing the one or more sensed optical characteristics of an at least one alternate general illumination lighting. The coax central conductor extends along the central axis.
