6SA7GT

The 6SA7GT is an octal pentagrid converter designed for amplitude-modulated superheterodyne receivers. Its multi-grid electrode system combines local-oscillator and frequency-mixer functions within one vacuum tube, producing an intermediate-frequency output from an incoming radio-frequency signal.
