ARCOTRON201
Telefunken Arcotron 201 is an early directly heated low-frequency amplification device intended specifically for resistance-coupled audio stages. Operating with a 1 V, 0.25 A filament, it was designed for use with high-value anode resistors and provided approximately fifteenfold circuit gain under specified conditions.
