ARCOTRON301
Telefunken Arcotron 301 is a gas-filled, directly heated detector designed for the Audion stage of resistance-coupled radio receivers. Its special construction permits detection with reduced sensitivity to low-frequency grid signals, using a 1 V filament and relatively high-value anode load resistance.
