Voltage - Triode (with diode, heptode or hexode) ·Diode-Diode-Diode-Triode

6S8GT

Triple-diode very-high-mu triode for multiple detector, discriminator, and control-voltage functions followed by voltage amplification. Three diode sections permit independent rectification while the triode provides substantial gain.
