ARDE
Ediswan ARDE is an early directly heated receiving triode for battery-operated radio equipment. Available in red-line and green-line characteristic variants, it was used in radio-frequency amplification, detection and initial audio-frequency amplification, with approximately 2 V filament operation and low plate-voltage requirements.
