Latest Patents
Walter W. Key is credited with a single patent titled "Audio Amplifier with Improved Stability." This invention addresses common issues in wide-band electronic AC amplifiers. It features a first stage that is directly coupled to a split-load phase inverter, RC coupled to a push-pull power output stage. The output is achieved through transformer coupling, with a portion of the output fed back to the cathode of the input stage for negative feedback. Key's design mitigates instability, such as the generation of high-frequency parasitics, by reducing the effective impedance seen by the control grids of the output tubes. To enhance high-frequency response while maintaining operational safety, adjustments to load and screen dropping resistors in the pentode section are implemented.
