"The No. 254A Vacuum Tube is a four-element, screen-grid tube for use as a radio-frequency power-amplifier and as a harmonic-generator at intermediate power levels at high frequencies. It may also be used as an oscillator at high frequencies where the reduced plate to control-grid capacity will be of advantage." Reference: https://www.westernelectric.com/s/254A.pdf.
